Summary

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.

A flaw was found in Docling, a tool for document processing. 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.

The vulnerability in Docling, rated Moderate, allows for sensitive file disclosure and denial of service within Red Hat OpenShift AI when processing untrusted METS-GBS archives. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H).

Weakness: CWE-611. Affected Red Hat products: Red Hat OpenShift AI 3.4.

Red Hat fixing advisory: RHSA-2026:60520.

Mitigation checklist

Recommended fix / mitigation
  • To mitigate this issue, avoid processing METS-GBS archives from untrusted or unverified sources. If processing such archives is unavoidable, ensure they are pre-validated within an isolated environment with strict resource limits to prevent resource exhaustion and unauthorized file access.
