Doc Text:
A flaw was found in Docling, a tool for document processing. The METS-GBS backend, responsible for parsing XML and detecting document formats, lacked sufficient security controls. This allowed an attacker to create specially crafted METS-GBS archives. When these archives were processed, they could lead to the exhaustion of system resources or cause the application to crash, resulting in a Denial of Service (DoS). Additionally, this vulnerability could also enable the disclosure of sensitive files.

Description OSIDB Bzimport 2026-06-26 16:03:34 UTC
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.
