Summary
A vulnerability in the Docling library versions 2.45.0 through 2.91.0 involves missing security controls in XML parsing within the METS-GBS backend and input document format detection. An attacker can craft malicious METS-GBS archives that, when processed, could read sensitive files, exhaust system resources, or cause application crashes.
Risk Assessment
The organization is at risk of sensitive data leakage, denial of service (DoS), and potential system damage due to resource exhaustion.
Recommendation
Immediately update the Docling library to version 2.91.0 or later, which contains the fix for this vulnerability.
Original NVD description (English source)
Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. From 2.45.0 until 2.91.0, the METS-GBS backend's XML parsing and the input document format detection lacked security controls. 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.
