Gotenberg: Server-Side Request Forgery (SSRF) in github.com/gotenberg/gotenberg/v8

Published May 14, 2026 CVSS 3.1 · 8.2 High EPSS < 1% KEV · Not listed
Description
Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.32.0, the LibreOffice conversion endpoint (/forms/libreoffice/convert) passes uploaded documents directly to LibreOffice without inspecting their content. LibreOffice then fetches any embedded external URLs on its own, completely bypassing the SSRF filters. This vulnerability is fixed in 8.32.0.
