CVE-2026-105743 is a medium-severity flaw (CVSS 4.0) 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 2.91.0 until 2.132.0, validate_url_safety in docling/backend/utils/image_resource_loader.py validates a hostname with a single IPv4 lookup and then allows the HTTP client to resolve and parse the original URL again, permitting DNS rebinding, mixed public and internal address records, and backslash authority parser di

docling docling UPGRADE

Affected: >= 2.91.0 and < 2.132.0

Fixed in: 2.132.0

Safe to downgrade to: a release before 2.91.0

1. Check installed version

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

2. UPGRADE to 2.132.0 (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 2.91.0 (Debian / Ubuntu)

apt-cache madison docling sudo apt install docling=<VERSION_BEFORE_2.91.0> 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_2.91.0> 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.
