Description

Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.34.0, Gotenberg's /forms/libreoffice/convert endpoint allows a specially crafted document to cause LibreOffice to automatically retrieve external HTTP(S) resources and local file resources during document conversion, enabling blind SSRF and limited local file disclosure via linked image resource loading. This issue is fixed in version 8.34.0.
