CVE-2026-24009
Impact
A PyYAML-related Remote Code Execution (RCE) vulnerability, namely CVE-2020-14343, is exposed in docling-core >=2.21.0, <2.48.4 and, specifically only if the application uses pyyaml < 5.4 and invokes doclingcore.types.doc.DoclingDocument.loadfrom_yaml() passing it untrusted YAML data.
Patches
The vulnerability has been patched in docling-core version 2.48.4.
The fix mitigates the issue by switching PyYAML deserialization from yaml.FullLoader to yaml.SafeLoader, ensuring that untrusted data cannot trigger code execution.
Workarounds
Users who cannot immediately upgrade docling-core can alternatively ensure that the installed version of PyYAML is 5.4 or greater, which supposedly patches CVE-2020-14343.
