medium Nessus 插件 ID 318727
语言：
简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- 在 postcss-selector-parser / 之前版本6.1.27.1.2中确定一个漏洞。影响的是组件 AST Serialization 的 src/selectors/container.js 文件的 toString 函数。执行操作可导致不受控制的递归。可以远程发起攻击。该漏洞已被公开披露，可能会被利用。升级到版本 6.1.3 并 7.1.3 能够解决此问题。此修补程序称为 5bc698cef66f8abd12610dc623e5d67cbc0f869d。建议升级受影响的组件。供应商解释说，根据他的定义，用户生成的 CSS 在服务器端的 DoS 对我们来说风险较低（因为大多数用户使用 PostCSS 编译自己的 CSS）。提交内容已向后移植到 6.x 下载次数最多的分支版本。（CVE-2026-9358）
请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
