Gotenberg is a PDF file API that, prior to version 8.31.0, did not validate keys in JSON objects sent to the /forms/pdfengines/metadata/write endpoint. Using a newline character in a JSON key allows for the injection of arbitrary ExifTool flags, leading to unauthenticated OS command execution.
- CVE-2026-40281Critical
