CVE-2026-42595— Gotenberg 代码问题漏洞

Gotenberg: Server-Side Request Forgery via Chromium URL Endpoint with Redirect-Based Deny-List Bypass

Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.32.0, Gotenberg's Chromium URL-to-PDF endpoint (/forms/chromium/convert/url) has no default protection against HTTP/HTTPS-based SSRF. The default deny-list regex only blocks file:// URIs. An unauthenticated attacker can point Chromium at any internal IP — including loopback, RFC 1918 ranges, and cloud metadata endpoints — and receive the response rendered as a PDF. Additionally, even when operators configure a custom deny-list, the protection is bypassed via HTTP redirects. Gotenberg's Chromium instance follows 302 redirects from an attacker-controlled external URL to internal targets without re-validating the redirect destination against the deny-list. This vulnerability is fixed in 8.32.0.

Gotenberg 代码问题漏洞

Gotenberg是Gotenberg开源的一个开发人员友好的 API。用于将多种文档格式转换为 PDF 文件。 Gotenberg 8.32.0之前版本存在代码问题漏洞，该漏洞源于Chromium URL转PDF端点缺乏HTTP/HTTPS SSRF默认保护，允许攻击者通过HTTP重定向绕过自定义拒绝列表，访问内部IP。
