Routine

MEDIUM 5.5UPGRADE

CVE-2026-44018 is a medium-severity flaw (CVSS 5.5) affecting docling. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

docling docling UPGRADE

Affected: >= 2.45.0 and < 2.91.0

Fixed in: 2.91.0

Safe to downgrade to: a release before 2.45.0

1. Check installed version

pip show docling

2. UPGRADE to 2.91.0

pip install --upgrade "docling>=2.91.0"

3. If no update is available yet, DOWNGRADE to a release before 2.45.0

pip index versions docling pip install "docling<2.45.0"

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
