Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem.

An attacker could craft malicious METS-GBS archives that, when processed, could read sensitive files, exhaust system resources, or cause application crashes. This vulnerability is fixed in 2.91.0.
