Gotenberg - Command Injection

Gotenberg 8.31.0 contains a command injection caused by lack of validation on JSON metadata keys in /forms/pdfengines/metadata/write endpoint, letting unauthenticated attackers execute OS commands, exploit requires crafted HTTP request. id: CVE-2026-42589 info: name: Gotenberg - Command Injection...

Gotenberg <= 8.30.1 - Server Side Request Forgery

Gotenberg is an API-based document conversion tool. In versions 8.30.1 and earlier, the default private-IP deny-lists for the --webhook-deny-list and --api-download-from-deny-list flags use a case-sensitive regular expression ^https?:// to match URL schemes. Because Go's net/url.Parse normalizes...

Gotenberg < 8.34.0 - Local File Disclosure

Gotenberg before 8.34.0 allows SSRF and limited local file disclosure via its /forms/libreoffice/convert endpoint. When LibreOffice is used to convert user-uploaded DOCX files, external relationships within the document such as a:blip r:link TargetMode="External" can instruct LibreOffice to fetch...

Gotenberg < 8.31.0 - Server-Side Request Forgery

Gotenberg before 8.31.0 is vulnerable to server-side request forgery SSRF due to insufficient validation of URLs in the downloadFrom API. An unauthenticated attacker can exploit the flaw by providing specially crafted IPv4-mapped IPv6 addresses such as http://::ffff:127.0.0.1 that bypass the...

POCCVE-2026-42589 针对影响 Gotenberg 的 CVE-2026-42589 的本地复现实验室及 nuclei 模板草稿。 摘要 CVE-2026-42589 是 Gotenberg 中一个未经认证的远程代码执行问题，由元数据键中的换行符注入引起，具体在： root@kitploit: POST /forms/pdfengines/metadata/write 受影响的 Gotenberg 将用户控制的元数据键转发给 ExifTool，且未拒绝控制字符。一个包含 JSON 转义换行符的元数据键可能被拆分为额外的 ExifTool 参数。 本实验室用于验证：...

CVE-2026-45742

Gotenberg is a Docker-powered stateless API for PDF files. From 8.10.0 until 8.33.0, the newContext function in pkg/modules/api/context.go starts one errgroup.Go goroutine for each multipart downloadFrom entry and allows those goroutines to concurrently write to the shared ctx.files,...

CVE-2026-45741

Gotenberg is a Docker-powered stateless API for PDF files. In 8.32.0 and earlier, the IsPublicIP function in pkg/gotenberg/outbound.go does not reject the 2002::/16 6to4 prefix, the 64:ff9b::/96 and 64:ff9b:1::/48 NAT64 prefixes, the fec0::/10 deprecated site-local prefix, Teredo, and other...

CVE-2026-44829

Gotenberg is a Docker-powered stateless API for PDF files. In 8.32.0 and earlier, filename handling in pkg/modules/api/context.go uses filepath.Base on Linux, which does not treat backslashes as path separators, so a multipart filename containing Windows-style parent directory components survives...
