PYSEC-2026-4207 Docling: Arbitrary local file read via draw:image xlink:href in the OpenDocument backend

Summary The ODF backend resolves the xlink:href of a draw:image element as a filesystem path whenever the referenced part is not found inside the document archive. The value comes straight from content.xml, so it is document content, and it is used with no scheme check, no confinement to the...

DeepTutor missing MCP tool authorization allows non-admin users to invoke unrestricted tools
