Routine

MEDIUM 4.3UPGRADE

CVE-2026-105747 is a medium-severity flaw (CVSS 4.3) 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 2.131.0, METS-GBS format detection in docling/datamodel/document.py and the backend in docling/backend/mets_gbs_backend.py call tarfile.TarFile.getmembers() before enforcing the max_member_count limit, causing the full archive member list to be allocated before the limit can stop processing.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

docling docling UPGRADE

Affected: >= 2.45.0 and < 2.131.0

Fixed in: 2.131.0

Safe to downgrade to: a release before 2.45.0

1. Check installed version

apt-cache policy docling || rpm -q docling || docling --version

2. UPGRADE to 2.131.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade docling

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade docling

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.45.0 (Debian / Ubuntu)

apt-cache madison docling sudo apt install docling=<VERSION_BEFORE_2.45.0> sudo apt-mark hold docling

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list docling sudo dnf downgrade docling-<VERSION_BEFORE_2.45.0> sudo dnf versionlock add docling

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.
