Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.136.Final and 4.2.16.Final, Netty's STOMP encoder ( StompSubframeEncoder ) does not escape or validate header values in  CONNECT  and  CONNECTED  frames, so raw newline ( \n ) characters in a header value are written directly to the wire, allowing an attacker who controls a header value to inject additio

Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.136.Final and 4.2.16.Final, Netty's HAProxy encoder ( HAProxyMessageEncoder ) writes AF_UNIX source and destination socket addresses into the HAProxy V1 text protocol without validating them for CRLF characters, so an attacker who controls an AF_UNIX address can inject  \r\n  sequences and split the sing

### Summary Req's multipart form encoder interpolates the per-part `name`, `filename`, and `content_type` directly into the part headers without escaping. An attacker who can influence any of those values can inject CRLF-separated header lines, smuggle additional form fields, or prepend a whole extra part into the request the victim service sends downstream. ### Details `Req.Utils.encode_form_p

Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, HttpPostRequestEncoder constructs multipart HTTP request bodies by directly concatenating user-supplied filenames and field names into Content-Disposition MIME headers without validating or sanitizing CRLF characters (\r\n). Since MIME headers are delimited by CRLF, an attacker w

### Summary `aiosmtplib`'s `SMTP.mail()`, `SMTP.rcpt()`, `SMTP.vrfy()` and `SMTP.expn()` send the caller-supplied email address to the server without rejecting embedded CR/LF (`\r\n`) bytes. An address that contains a CR/LF is written verbatim onto the SMTP control connection, so the bytes after the CRLF are framed by the server as one or more **additional, standalone SMTP command lines**. A call

The WPForms – Easy Form Builder for WordPress – Contact Forms, Payment Forms, Surveys, & More plugin for WordPress is vulnerable to Improper Neutralization of CRLF Sequences ('CRLF Injection') in all versions up to, and including, 1.10.2 This is due to `get_reply_to_address()` processing the Reply-To display name through smart-tag expansion with context `'notification'` instead of `'notification-r

### Summary CRLF injection in hackney's WebSocket upgrade request builder (`src/hackney_ws.erl`). `init/1` copies the `host`, `path`, `headers`, and `protocols` options from the caller-supplied opts map verbatim into `#ws_data{}`, and `do_handshake/1` splices them directly into the raw HTTP/1.1 upgrade request by binary concatenation with no `\r\n` or `\0` stripping. A caller that passes any of t

### Summary `hackney_url:make_url/3` passes the URL query component directly into the HTTP/1.1 request target without percent-encoding `\r` or `\n`. RFC 3986 §3.4 requires characters outside the query grammar to be percent-encoded, but no validation or escaping occurs. An attacker who controls any portion of the URL passed to hackney can inject raw CRLF sequences into the request line, enabling H

### Summary CRLF injection in `hackney_cookie:setcookie/3` (`src/hackney_cookie.erl`). The function validates `Name` and `Value` against CR/LF and control characters but concatenates the `domain` and `path` options verbatim into the output binary. If either option carries attacker-controlled data, a `Host` header forwarded as the cookie domain, a request URI forwarded as the cookie path, a `\r\n`

Jenkins Script Security Plugin 1402.v94c9ce464861 and earlier does not reject Groovy AST transformation annotations carrying an extensions member, allowing attackers able to run sandboxed Groovy scripts to execute code outside the sandbox if a suitable script is present on the classpath of the component that evaluates the script.

Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Prior to 0.6.5 and 0.5.15, when Net::IMAP#id is called with a hash argument, although the ID field value strings are correctly quoted (escaping quoted specials), they were not validated to prohibit CRLF sequences. While Net::IMAP#enable does process its arguments for aliases, it does not validate them as val

Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Prior to 0.6.5 and 0.5.15, several Net::IMAP commands accept a "raw data" argument that is sent verbatim after validation to prevent command injection. However, if a server does not support non-synchronizing literals, it may still be possible to inject arbitrary IMAP commands inside non-synchronizing literal

AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.0, attacker-controlled input included into multipart/payload headers can be used to modify a request to inject additional headers or similar. In the unlikely situation that an application is passing user-controlled strings into MultipartWriter.append(headers=...) or Payload.headers, then an attacker may b

Net::Statsite::Client versions through 1.1.0 for Perl allow metric injections. Net::Statsite::Client is a client for the statsite protocol, which is a variant of statsd. Newlines are not removed from metric names, allowing metric injections. Values are not sanitised for newlines or other protocol control characters such as colons or pipes, allowing metric injections.

form-data is a library for creating readable multipart/form-data streams. In versions through 4.0.5, the `field` argument to `FormData#append` and the `filename` option are concatenated verbatim into the `Content-Disposition` header without escaping carriage return (CR), line feed (LF), or double-quote (") characters. An application that passes attacker-controlled data as a field name or filename

The 'clientId' parameter from incoming HTTP requests is directly concatenated into OAuth2 server log warning messages without sanitizing control characters. This allows an attacker to inject arbitrary content, including fake log entries, into the server's log files. Users are recommended to upgrade to versions 4.2.2 or 4.1.7, which fixes this issue.

guzzlehttp/psr7 is a PSR-7 HTTP message library implementation in PHP. Versions prior to 2.10.2 did not reject ASCII control characters, whitespace, or DEL in first-party URI host components. A vulnerable flow is: First, an application accepts a user-controlled URL. Second, the URL is used to construct a PSR-7 `Uri` or `Request`. Third, the host component contains CRLF or another header-unsafe cha

CVE-2026-8722 影响 Perl 模块 Net::Async::Statsd::Client 版本 0.005 及之前。该模块用于向 StatsD 服务发送指标数据，但未对指标名称中的换行符（\n）、冒号（:）和管道符（|）进行过滤。攻击者如果能够控制指标名称的输入源（如用户输入、外部数据），则可能通过注入特殊字符插入额外的恶意指标，从而操纵 StatsD 收集的数据。这可能导致监控系统失真、触发错误告警或掩盖真实攻击行为。由于 StatsD 通常用于聚合和存储时间序列数据，注入的指标可能被后续处理工具（如 Graphite、Grafana）错误解析，造成数据污染。该漏洞的利用复杂度较低，但需要攻击者具备对指标名称生成的控制能力。官方尚未发布补丁，建议开发者升级到更新版本（若存在）或自行在调用模块前对指标名称进行过滤。此外，应限制模块的网络暴露范围，仅允许可信源发送指标数据。

Improper Neutralization of CRLF Sequences ('CRLF Injection') vulnerability in elixir-mint Mint allows HTTP Request Splitting and HTTP Request Smuggling.
