CVE-2026-42596
严重CVE-2026-42596 是什么?
Gotenberg 是一个由 Docker 支持的 PDF 文件无状态 API。 Prior to 8.31.0, the default deny-lists used by Gotenberg's downloadFrom feature and webhook feature are bypassable.由于过滤器基于正则表达式且区分大小写,因此未经身份验证的攻击者可以提供 http://[::ffff:127.0.0.1]:... 等 URL,并访问默认拒绝列表旨在阻止的环回或私有 HTTP 服务。 This crosses a real security boundary because an external caller can force the server to make outbound requests to internal-only targets.该漏洞已在 8.31.0 中修复。
