A flaw was found in Evolution. A remote attacker can exploit this vulnerability by sending a specially crafted HTML email containing a spoofed vCard control. When a victim clicks on this control, Evolution's trusted JavaScript handler incorrectly assigns an attacker-controlled JavaScript URL to an iframe's source. This action leads to arbitrary JavaScript execution within the mail-viewing context,

JupyterLab before 4.5.9 contains a stored cross-site scripting vulnerability in the Extension Manager that fails to validate URI protocols in package metadata URLs. Attackers can publish malicious PyPI packages with javascript: URLs in project metadata that execute arbitrary JavaScript in the JupyterLab origin when users click the extension name.

JupyterLab 在 4.5.9 之前的版本中，扩展管理器存在一个存储型跨站脚本（XSS）漏洞。该漏洞源于扩展管理器在解析包元数据 URL 时未能验证 URI 协议。攻击者可以在 PyPI 上发布恶意的 Python 包，在项目元数据中嵌入 javascript: 协议的 URL。当用户点击扩展名称时，恶意 URL 会触发任意 JavaScript 代码在 JupyterLab 的源环境中执行。由于 JupyterLab 通常运行在本地回环地址并拥有较高的用户权限，攻击者可能通过此漏洞窃取用户的会话凭证、访问令牌，或修改用户的笔记本文件。该漏洞的 CVSS 评分为 6.1（中等），攻击复杂度低，需要用户交互，但可造成机密性和完整性的轻微损失。目前没有证据表明该漏洞已被在野利用，也未列入已知被利用漏洞（KEV）清单。建议用户尽快升级至 JupyterLab 4.5.9 或更高版本，并考虑限制扩展管理器的网络访问，避免安装来源不明的扩展包。

Dashy is a self-hostable personal dashboard. From 1.9.4 until 3.2.0, the Dashy RSS Widget in src/components/Widgets/RssFeed.vue does not sanitize RSS item link values before rendering feed item titles and Read More links as anchor href attributes, allowing an attacker-controlled feed to provide a javascript: URI that executes when clicked in the Dashy origin. This issue is fixed in version 3.2.0.
