## SAML Tenant Binding Enables Cross-Tenant Account Takeover
### Summary
Prowler's SAML authentication flow trusted the email domain asserted in a SAMLResponse when deciding which tenant should receive the final token. A malicious tenant with its own SAML configuration and a self-controlled IdP could complete a valid SAML flow for its own configured domain, while asserting an email address from
### Summary
`rclone serve s3`'s handler chain, when `--auth-proxy` is configured, is (outermost first): `authPairMiddleware` -> `proxyAuthMiddleware` -> gofakes3's own SigV4-verifying handler.
`authPairMiddleware` parses the accessKeyID straight out of the incoming request's own `Authorization` header (entirely client-controlled) and registers `{accessKey: ws.s3Secret}` into gofakes3's shared cre
Requests from the reverse proxy to the identity-provider service for token discovery, introspection, and credential exchange do not verify the identity provider's server certificate. An attacker positioned on the network path between the proxy and the identity provider could impersonate the identity provider and issue forged authentication tokens accepted by the deployment.
When a particular authentication mode is configured, the reverse proxy forwards requests for a bundled third-party administrative interface directly to that interface without applying the gateway's own authentication requirement first. All access control for this administrative interface, which manages the credential store used to gate every other service in the deployment, is delegated entirely t

## Summary
Open WebUI's OAuth token exchange endpoint issues a session for a provider access token without running the OAuth role management that the normal OAuth login callback runs. A user whose provider roles the login callback would refuse, or would demote, could still obtain a working session at their existing role through this endpoint.
## Preconditions
- `ENABLE_OAUTH_TOKEN_EXCHANGE=True`.
## Summary
Traefik accepts an HTTP/1.x request whose request-target is in rootless / opaque form (for example `GET http:http://internal-vhost/admin HTTP/1.1`). Go parses this into `URL.Opaque` with an empty `URL.Path`, so Traefik evaluates all routing, path-sanitization, middleware and access-log decisions against a path that normalizes to `/`, while the proxy forwards the attacker's original tar
## Summary
In SSE/HTTP transport mode, `mysql_mcp_server` constructs `SseServerTransport` without passing `security_settings`. As a result, the MCP Python SDK's DNS-rebinding protection (Origin/Host header validation) is disabled; the Starlette application has no CORS or TrustedHost middleware; and the service binds to `0.0.0.0` by default with no authentication on any route.

## Summary
There is a high-severity request-smuggling vulnerability in Traefik's handling of the HTTP/1.1 `Upgrade` mechanism. Since Traefik moved to unencrypted HTTP/2 with prior knowledge (Go 1.24), a client-initiated `Upgrade: h2c` request header and its connection-specific `HTTP2-Settings` header were forwarded to the backend. A backend that honours the h2c upgrade and answers `101 Switching
I identified an attacker using a semi-autonomous coding agent to run an offensive operation: finding poorly secured LLM resale gateways, acquiring API access through ordinary web flaws and account farming, validating the resulting inference capacity, and aggregating it behind a single gateway of their own.

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.7 before 19.1.8, 19.2 before 19.2.6, and 19.3 before 19.3.2 that, under certain conditions, an unauthenticated user could have read arbitrary files from the GitLab server due to improper path confinement and missing authentication enforcement in the repository commits API.
A file-upload handler redirects the authenticated client's browser to a URL taken directly from that same request's Referer header, without validating it against the application's own origin. This allows an authenticated attacker to craft a request that causes another user's browser to be redirected to an arbitrary external destination after completing an upload.
A web interface reflects a portion of the request URL into a script context and a hyperlink attribute without adequate encoding, and does not require authentication to reach. This allows an unauthenticated network attacker to craft a link that, when visited by a user, executes arbitrary script in the context of the affected application and can redirect the user's browser to an arbitrary external s
### Summary
A flaw in the external identity provider handler allows unauthorized account linking to occur under specific administrative configurations. When auto-linking by email is enabled, ZITADEL checks that the local user's email is verified, but does not explicitly cross-check whether the incoming external identity provider (IdP) also verified that email address upstream.

### Summary
A token lifecycle validation vulnerability was discovered in ZITADEL's external JWT Identity Provider (IdP) implementation

## Summary
The FTP auth-proxy driver stores one obscured password per username in a server-wide map. It does not bind the credential or returned VFS to the authenticated FTP session. If two accepted credentials use the same username but resolve to different proxy backends, the later login overwrites the map entry. Subsequent operations on the first, still-authenticated session are re-authorized w
这篇论文研究的是网络安全测量研究中一个长期被忽视但影响深远的方法论问题：抽样策略如何影响测量结果的有效性与可推广性。背景是，大规模 Web 安全测量（例如统计某种漏洞、错误配置或协议实现问题的普遍程度）通常依赖 Tranco、Common Crawl 等公开域名数据集，但由于对每个域名执行深度检测（如 TLS 扫描、页面内容分析、指纹识别）成本高昂，研究者几乎不可能穷尽全量数据，只能进行抽样。然而，抽样实践在很大程度上是「约定俗成」而非「证据驱动」的：最常见做法是取排序列表中的 Top N 个域名。作者指出，这种惯例是否引入系统性偏差、是否扭曲观测到的漏洞/问题发生率、是否导致不同研究之间无法横向比较，此前缺乏系统性评估。
该工作据作者所述是首个对抽样方法如何影响测量结论的全面研究。方法上包含两部分：一是对既有 Web 安全测量文献的系统性综述，梳理社区实际使用的数据集与抽样方式；二是大规模实测，覆盖 50 万个 Tranco 主机与 2480 万个 Common Crawl 主机，对不同数据集与不同抽样策略进行对比评估，包括 Top N 确定性抽样、基于概率的抽样以及二者的混合策略。
主要结论有四点：(1) Top N 抽样虽有其合理性（例如更贴近真实用户流量、更受关注），但研究者必须清醒认识到它并不反映 Web 的整体分布，因此基于 Top N 得到的流行率/危害估计不能直接外推到全网；(2) 基于概率的抽样策略能够给出稳定且无偏的流行率估计，并且在多种「影响评估」目标上同样有效；(3) 混合抽样相对纯概率抽样没有任何优势，其确定性的前缀部分对准确度持续产生负面影响；(4) 基于上述证据，作者给出面向后续研究的可操作建议，提出采用「自适应概率抽样」策略，即使目标问题的真实流行率未知，该策略依然保持有效。论文面向的读者是从事大规模 Web 测量、安全实证研究、互联网基础设施普查的研究者与安全团队。
💡 推荐理由: 安全团队常用 Top N 域名榜单来评估漏洞或配置问题的普遍性，并据此排优先级。该研究证明这种做法并不代表全网分布，会系统性高估或低估风险面；改用概率抽样可获得稳定无偏估计，直接影响测量结论的可信度与决策依据。

GetSimple CMS is a content management system (CMS), and GetSimple CMS CE is the community edition of that CMS. A logic flaw in GetSimple CMS (v3.4.0a and below) and GetSimpleCMS-CE (v3.3.22 and below) allows unauthenticated attackers to create a new administrator account. The application features an automated security control designed to delete the sensitive `admin/setup.php` file post-installatio
An improper authentication vulnerability in the WS-Security (wsse:UsernameToken) verification routine within the Sofia IPC daemon in Xiongmai IP Camera XM530 firmware HMT.CM2005-v220608.1837 and earlier allows remote attackers to bypass authentication and execute privileged ONVIF actions (including PTZ control, stream URL retrieval, and system reboot) via a crafted SOAP request supplying the admin
Authorizer is an open-source, self-hostable authentication and authorization server. Prior to version 2.2.1, the `/authorize` endpoint accepts any `redirect_uri` without validating it against `AllowedOrigins`. When `response_type=token` or `response_type=id_token`, the server appends `access_token`, `id_token`, and `refresh_token` as query parameters and issues a 302 redirect to the attacker-suppl
SPIP before 4.4.18 contains a remote code execution vulnerability in the editer_objet action where the arg parameter resolves SQL table names without enforcing an editable columns allowlist, allowing attackers with a valid nonce to inject attacker-controlled rows into the spip_jobs table. Attackers can supply arg=job/0 with crafted fonction and args values, which are later unserialized and execute
SPIP before 4.4.18 contains a missing authorization vulnerability in the administrative action endpoints under ecrire/action/ that allows unauthenticated attackers to perform privileged actions by supplying a valid HMAC-SHA256 nonce without any server-side permission check via autoriser(). Attackers can obtain a valid nonce, compute it for any action as the anonymous user, and invoke the editer_au
An issue in Robotics-STAR-Lab (SYSU STAR Group) RACER Tested affected version: commit abcdef1234567890 allows an attacker to cause unsafe trajectory planning and potential UAV collisions via a missing default case in the FSM that stops publishing swarm trajectories when the drone enters IDLE
Hugo is a static site generator. From v0.161.0, Hugo executes Node tools under Node's permission model, but TailwindCSS — included in the default security.exec.allow list — requires a highly permissive configuration (--allow-addons, --allow-child-process, --allow-worker). As a result, the restrictions intended by the fix for GHSA-x597-9fr4-5857 could still be bypassed, allowing a Node tool invoked
The advanced-customized-prompts WordPress plugin through 1.0.1 does not verify the password before issuing an authenticated session for a supplied email address in an unauthenticated action, allowing unauthenticated attackers to log in as any registered user, including administrators, or to create arbitrary new accounts.
The teddy-bear-customize-addon WordPress plugin through 1.0.5 does not properly validate uploaded files, relying on a client-supplied content type and preserving the original filename, allowing unauthenticated attackers to upload arbitrary PHP files and execute code on the server.
The teddy-bear-customize-addon WordPress plugin through 1.0.5 does not verify a user's password before authenticating them, allowing unauthenticated attackers to log in as any registered user, including administrators, by supplying only that user's email address.
The MIPL Grouped Checkout Fields for WooCommerce – Customize & Organize Checkout Fields. plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the `mipl_wc_upload_file` function in all versions up to, and including, 1.2.1. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote
IBM DataStage on Cloud Pak for Data 5.4.0.0 could allow a remote authenticated attacker to obtain sensitive information and bypass security restrictions due to improper authentication.
IBM DataStage on Cloud Pak for Data 5.4.0.0 could allow a remote authenticated attacker to cause a denial of service due to a path traversal vulnerability.
IBM DataStage on Cloud Pak for Data 5.4.0.0 could allow a remote authenticated attacker to create arbitrary files due to path traversal during archive extraction.
IBM Langflow OSS 1.0.0 through 1.11.5 could allow a remote attacker to execute arbitrary OS commands due to improper neutralization of special elements used in an OS command.
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, a protocol change while processing HTTP/2 traffic could lead to type confusion in Suricata.

IBM Common Licensing Agent 9.0, Agent 9.0.0.1, Agent 9.0.0.2, ART 9.0, ART 9.0.0.1, and ART 9.0.0.2 could allow a remote attacker to redirect users to an arbitrary domain due to improper validation of the HTTP Host header.
IBM Langflow OSS 1.0.0 through 1.11.5 Langflow could allow an unauthenticated attacker to execute arbitrary code and access or modify chat sessions through publicly shared MCP project endpoints due to improper enforcement of public-flow security restrictions and session isolation controls.
A vulnerability was reported in Lenovo Health Android Application, distributed exclusively in the Chinese market, that could allow an attacker to access sensitive health-related information.
passport-saml-encrypted through 0.1.13 makes SAML signature verification conditional on an optional cert option, allowing attackers to bypass authentication by submitting unsigned SAML responses. Attackers can post forged SAML responses with arbitrary NameID and attributes to the assertion consumer service endpoint to receive authenticated profiles without valid signatures.
QloApps through 1.7.0 renders back-office list filter POST parameters into HTML input value attributes without escaping them in the list helper template. Attackers can induce authenticated users to submit crafted POST requests with malicious payloads to list controllers, executing arbitrary JavaScript in the victim's session to read administrative data and perform actions.
starlette-admin versions 0.16.1 through 0.17.1 fail to enforce the searchable_fields allowlist when configured as an empty list, allowing authenticated users to filter on non-searchable fields. Attackers can submit structured filter queries via the list API's where parameter to perform equality and comparison operations on excluded columns.
An example environment-configuration file for a bundled inventory-management component ships with a fixed, publicly-known administrative password. A deployment that copies this example file into active configuration without running the setup routine that regenerates credentials will expose that component's administrative interface to anyone aware of the default value.
A prior update that raised a bundled HTTP client library to a version remediating known vulnerabilities was later reverted, reintroducing the earlier, vulnerable version into a log-processing component. The only code path in that component using the library issues a request to a single fixed, trusted vendor URL at initialization and does not process attacker-controlled input through the library, l
The administrative password is hashed using a comparatively weak, fast algorithm for the credential store backing one authentication path, and the file containing that hash is written with permissions allowing it to be read by any local user. This is inconsistent with a separate, stronger hashing algorithm used for the same password on another authentication path. A party able to read this file, i
An issue was discovered in OpenStack Keystone before 29.0.3. Tokens obtained via delegated authentication methods (EC2 credentials, application credentials, OAuth1 access tokens, and trusts) are not blocked from creating, modifying, or deleting credentials via the /v3/credentials API. EC2-derived tokens can additionally read credential blobs, exposing TOTP MFA seeds and other secrets. Also, PATCH

An example environment-configuration file ships with a fixed, publicly-known secret value used to sign authentication cookies for a bundled packet-analysis component. A deployment that copies this example file into active configuration without running the setup routine that regenerates the value will use the known default, allowing an attacker aware of the default to forge valid authentication coo
A deployment mode intended to expose only read access to a bundled packet-analysis component's interface denies a list of write-capable routes by pattern, but the pattern omits routes that modify tags attached to stored session records, and the proxy configuration otherwise permits the request method those routes use. This allows an authenticated user on a deployment intended to be read-only to ad
stb_vorbis through 1.22 contains a heap buffer overflow in start_decoder() where the codebook multiplicands allocation size is truncated from size_t to int. Attackers can craft a malicious Ogg Vorbis file with large entries and dimensions values to trigger out-of-bounds writes, causing process crashes or heap corruption.
A deployment mode intended to expose only read access to stored data proxies a set of application programming interface routes without restricting which request methods are allowed. One such route accepts a request that creates or overwrites a stored record, including an attacker-chosen identifier, using the application's own elevated backend credentials. This allows an authenticated user on a dep
The application's role-authorization lookup defaults to granting access when a request handler's name is not present in its table of role requirements, rather than defaulting to deny. Any request handler that is not explicitly registered in this table is reachable by any authenticated user regardless of their assigned role, and any newly added handler is fail-open by default until explicitly added
A routing rule selects between two different authentication mechanisms for the same downstream service based on the value of a client-supplied request header, rather than on any property the client cannot control. An authenticated user in possession of a shared service credential can set this header to route around the primary role-based authorization check and reach the alternate path's fixed, el
An application programming interface endpoint accepts a user-supplied value and interpolates it directly into the path of a backend request to the underlying search and analytics data store, without restricting its contents. This allows an authenticated attacker to substitute an arbitrary backend path, causing the application's own elevated service credentials to be used against unintended interna
A file-transfer interface that requires valid credentials accepts attacker-controlled filenames without restricting shell metacharacters. An automated process later constructs and runs a system command using the uploaded file's name, allowing an authenticated attacker to embed and execute arbitrary operating system commands with the privileges of that process. This allows an attacker to read and m
An interface that accepts file uploads from authenticated users extracts the contents of uploaded archives without validating that extracted file paths remain within the intended destination directory. This allows an authenticated attacker to craft an archive whose entries traverse outside the destination directory, causing the extraction process to write files to arbitrary locations with the priv

A `FILE` response whose `filePath` embeds request data (e.g. `"/srv/public/{{queryParam 'name'}}"`, the documented way to let the client pick a file) is confined by `getSafeFilePath` with `resolvedPath.startsWith(staticBaseDir)`. That prefix test has no path-separator boundary, so a `../`-escaped path whose absolute form string-prefixes the base directory passes. An unauthenticated cli

Concrete CMS Area API's block-create endpoint in versions 9.2.0 to 9.5.2 did not invoke the block type controller's validate() method on submitted data, which, for file-referencing blocks such as hero_image and gallery, is where the referenced file is authorized against the user's file-manager visibility. As a result, an authenticated user holding the block-add scope could store, and cause the pag
Concrete CMS 9.5.2 and below is vulnerable to Cross-Site Request Forgery (CSRF) in the Express "Clear Entries" function (POST /index.php/dashboard/system/express/entities/delete_entries) because the controller records but does not enforce a failed CSRF token check, allowing the destructive operation to proceed when the token is missing or invalid.

该论文聚焦于一个长期存在的安全工程问题：即时通信协议的「形式化规范保证」与「实际运行实现行为」之间存在落差。Signal 协议为数以十亿计的用户提供加密通信，是 WhatsApp（全球用户量最大的消息应用）与 Signal 官方客户端的底层协议；学界已在计算模型与 Dolev-Yao 符号模型下对该协议给出大量强安全证明，但这些证明只覆盖协议规范本身，无法说明真实客户端在运行时是否严格按模型执行。作者的工作是填补这一差距：采用新近提出的运行时监控器 SpecMon，对实际观测到的执行轨迹进行一致性检查，判断其是否符合形式化协议模型。为此，作者对两个真实应用（WhatsApp Web 与 Signal Desktop）进行插桩，捕获它们与网络层及密码学组件之间的交互事件；在可信事件抽取的前提上，把运行时行为抽象为符号层，再据此构建两个与 Tamarin 兼容的多重集重写（multiset-rewrite）模型以便形式化验证。论文给出了首个 WhatsApp Web 上 Signal 协议实现的模型，以及迄今为止最详细的 Signal 原始协议模型。监控结果显示，在给定的抽取与符号抽象假设下，观测到的执行符合这些模型，并对 Signal 协议的核心组件验证了认证性与机密性属性。值得注意的是，监控还暴露出原始 libsignal 库与 WhatsApp 分支之间此前未被文档记录的行为差异。作者同时评估了方法的可复现性与实用性：完成 WhatsApp Web 建模、应用插桩、加入模糊测试并运行实验共耗时三个人周；实验表明可对真实应用进行高效监控，并能检测人为注入的安全故障，在其实测环境中开销较低。

本文对基于大语言模型（LLM）的自动化渗透测试智能体（pentest agent）能力演进做了实测跟踪。作者选取两个都构建于 PentestGPT 之上的系统进行对比：一个是较早期的、采用人在回路（human-in-the-loop）模式的系统，底层使用开放权重模型 Kimi K2.5；另一个是较新的全自主系统，底层使用 Claude Opus 4.8。在三个公开靶机上的测试中，自主系统全部攻克三台目标，其中包括人在回路系统始终未能完成的两台。作者认为更值得注意的反而是旧系统的表现：即使在未能拿下的靶机上，它仍完成了约一半的子任务，而且整套系统只运行在普通的大学 GPU 上、没有云厂商的安全护栏介入。作者坦承，由于模型、控制框架（harness）、自主程度与记忆架构在同一实验中同时发生变化，只能描述趋势而无法做归因解释。随后作者提出下一个关键问题：当任务复杂度继续上升时，什么会成为这类智能体的上限？业界通常的答案是长时程记忆，即在长时间攻击链中丢失先前发现。作者通过给两个系统都加装覆盖度记忆（coverage-memory）层来检验这一假设，结果两者成绩均未提升。在可复盘的旧系统失败运行中，真正的瓶颈看起来是规划与承诺（planning and commitment），而非记忆丢失：智能体已经掌握了通往下一步的证据，却没有把它转化为具体的利用假设。作者据此推测，攻击性能力的进步更多取决于智能体的规划能力，而非记忆容量。最后作者指出，用于追踪该能力的同一套子任务评分体系对防御方同样可用，使其能够在能力爬升阶段就持续度量，而不必等到在真实环境中遭遇。研究视角上，本文属于能力评测与趋势追踪类工作，适合 AI 安全、红队/紫队、SOC 与安全战略规划人员阅读。

拜占庭协议（BA）是分布式系统的核心基础组件，多实例执行下的安全性分析近年受到越来越多关注。然而现有敌手模型大多只考虑节点被腐化，忽视了通信信道被对抗性操纵带来的重要威胁。攻击者可通过信道攻击在多个协议执行实例之间对消息进行重排序，从而破坏协议的安全保证。本文提出首个将节点腐化与信道攻击相结合的敌手模型，并基于该模型为并行组合与并发组合下的拜占庭协议建立了新的安全阈值，给出互相匹配的不可能性与可能性结果，形成紧界。不可能性方面：即使采用认证拜占庭协议，当 n ≤ 3t 或 n ≤ 2c + 2t + 1 时，在并行组合下也无法保证安全，其中 t 为被腐化节点数，c 为通信信道数，n 为节点总数。可能性方面：作者证明当 n > max{3t, 2c+2t+1} 时，未认证拜占庭协议在并行与并发组合下存在安全协议。为此，作者首先给出通用黑盒编译器，可将任意单实例安全的 BA 协议转换为在并行与并发执行下安全，且不引入额外安全假设；为优化性能，进一步利用纠删码设计精化编译器，显著降低通信开销，尤其对长消息可达到相对原协议的常数倍乘性开销，从而保持相同的渐近通信复杂度。该工作为多实例协议的组合安全分析提供了首个同时涵盖节点腐化与信道重排序的模型与紧界，并给出可落地的通用与优化编译方案。
💡 推荐理由: 分布式系统与区块链共识普遍依赖“单实例安全即可组合”假设。本文指出信道重排序可跨实例破坏 BA 安全，并给出可组合安全阈值与编译器，对多实例协议部署与安全评估有直接指导意义。

观察性研究中的平均处理效应（ATE）估计是社会科学、医学和流行病学等领域广泛使用的基础统计工具，用于在无法进行随机对照试验时评估某种干预或暴露对结果变量的因果影响。然而这些领域所处理的数据通常包含高度敏感的个人信息，直接发布基于原始数据的 ATE 估计会带来隐私泄露风险，因此研究者一直希望获得满足差分隐私（Differential Privacy）保证的 ATE 估计算法。本文针对这一需求提出了两种基于倾向得分（propensity score）的 ATE 估计机制：第一种是对先前工作中使用的逆概率加权（IPW, Inverse Probability Weighting）方法进行改进，使其在差分隐私约束下具有更优的统计性质；第二种则采用倾向得分分块（BPS, Blocking on Propensity Score）策略，即先估计每个样本接受处理的倾向得分，再依据得分将样本划分为若干同质区块，在区块内进行差分隐私化的效应聚合与估计。作者从理论上分析了两种算法的误差与偏差来源，并在实验中与既有方法进行了对比。结果显示，两种新算法在相同隐私预算下均表现出更低的估计误差和更小的偏差；其中基于倾向得分分块的算法提升尤为显著，相较于先前工作常常将误差降低 75% 甚至更多。这意味着在保持同等隐私保护强度的前提下，可以显著提升因果效应估计的可用性与准确性，对需要在敏感数据上开展因果推断的场景具有直接的实用价值。论文属于方法论与统计机器学习交叉方向，适合差分隐私、隐私增强技术以及因果推断相关的研究人员与隐私工程从业者阅读。
💡 推荐理由: 在医疗、社会科学等敏感数据场景中，因果效应估计本身可能泄露个体信息。本文把差分隐私与 ATE 估计结合，并在误差上大幅优于先前工作，为隐私保护型因果推断提供了更可用的方案，安全与隐私工程团队在做 PET 选型与隐私预算评估时值得参考。

nfsd: add fh_want_write() for early-verified SETATTR in nfsd_proc_setattr()
The BOTH_TIME_SET branch calls fh_verify() early so setattr_prepare()

sctp_endpoint_bh_rcv() looks the association up only when chunk->asoc is
NULL, and caches the result in chunk->asoc and chunk->transport without

In version 5.5.3 and earlier, UNICHARSET::load_via_fgets in src/ccutil/unicharset.cpp trusts the declared unichar count as a loop bound and uses id as an unchecked index into the unichars vector. unichar_insert_backwards_compatible can leave the vector unchanged for an empty, duplicate, or already-encodable representation, causing id to become larger than un
Tesseract is an open source OCR engine. In version 5.5.3 and earlier, FullyConnected::DeSerialize in src/lstm/fullyconnected.cpp does not validate the deserialized layer scalars ni_ and no_ against the weight-matrix dimensions. During FullyConnected::Forward, MatrixDotVector in src/lstm/weightmatrix.cpp writes w.dim1() results into temp_line, which is sized from no_, and reads w.dim2() minus one i
Tesseract is an open source OCR engine. In version 5.5.3 and earlier, Classify::ReadNormProtos in src/classify/normmatch.cpp parses the NORMPROTO component of a .traineddata file and uses std::istream::operator>>(char*) to extract a whitespace-delimited token into a fixed 61-byte stack buffer without setting a stream width. The 100-byte line buffer can carry a token of up to 99 characters, so a to
FileRun before 2026.3.0 contains an OS command injection vulnerability caused by a no-op redefinition of escapeshellcmd() in CLI.php that strips shell-metacharacter escaping, allowing attacker-controlled input to reach an exec() sink unsanitized. Attackers can exploit this through an interactive path via image_preview.php with a crafted args parameter requiring superuser authentication, or through
本文从形式语言理论的角度重新审视 Emil Post 提出的“生产性集合”(productive set) 概念，并据此构造出本质上不可判定的形式文法。背景上，Post 证明存在这样一类自然数集合：它们不是递归可枚举的，甚至连半可计算都做不到——不存在任何图灵机能在有限步内枚举其全部元素，其补集可被递归枚举而集合自身不可枚举，这类集合即生产性集合；若进一步满足更强条件则称为“完全生产性”。由此可推出，任何以生产性集合作为其词集的形式语言都不可能是递归可枚举的，也就是无法被图灵机半判定，属于“本质不可判定”的语言，其地位比乔姆斯基体系中最宽的第 0 型递归可枚举语言还要“超出图灵阈值”。论文的核心方法是：把 Post 关于自然数生产性集合的经典构造（通过不断产生“新元素”，使任何候选枚举器都无法封闭其输出集合）翻译到文法规则设计中，从而显式构造出一族能够生成生产性词集的形式文法，并论证这些文法所定义的语言既不可计算也非递归可枚举。作者明确指出这是一项构造性、概念性的理论工作，而非实验性研究：其贡献在于把可计算性理论中关于不可判定性的经典边界结果系统地带入形式文法与语言层级的语境，给出“超越图灵可判定性”的文法形式刻画，并提示语言层级中存在位于递归可枚举语言之上的层次。适合可计算性理论、形式语言与自动机理论的研究者阅读，也适合关心程序分析、形式验证与静态分析工具判定边界的工程读者。
A lot of this week’s security news has the same awkward answer to one question: “Why was that allowed to work?”
An extension asks for access and takes too much. A trusted service becomes part of a phishing chain. An old bug still gets results. An exposed system stays exposed. A package looks useful right up until it isn’t. Different stories, same basic problem: the path in was often already

Seven of the thirteen Linux privilege escalation CVEs we tracked in 2026 turned out to be the same copy-on-write bug pointed at different kernel interfaces. We ran the public proof-of-concept for eleven exploits and two misconfigurations, and noted which rules fired.
Anthropic has warned that cybercriminals and state-sponsored hackers alike are using its Claude models for cyber attacks, weapons design, propaganda, and mass surveillance between December 2025 and August 2026.
The threat actors, which the artificial intelligence (AI) company has branded Generative Threat Groups (GTGs), span state-sponsored groups, financially motivated criminals, commercial
Anthropic on Thursday revealed it disrupted a campaign mounted by a Russian state-sponsored threat actor that abused Claude for developing an AI-assisted workflow to get ahead of the detection curve.
The operation has been attributed to a cyber espionage group it calls GTG-20006 (where "GTG" stands for Generative Threat Group), which aligns with broader reporting linking the cluster to Midnight
