CVE-2026-40893
Gotenberg is a Docker-powered stateless API for PDF files.
Published May 14, 2026 · updated Jun 17, 2026 · thecodingmachine gotenberg
Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.31.0, Gotenberg only checks if the tag is exactly FileName, so System:FileName slips right through and ExifTool happily renames the file. This allows remote attackers to move, rename, and change permissions for arbitrary files. This vulnerability is fixed in 8.31.0.
