PYSEC-2026-1313
docling-core vulnerable to Remote Code Execution via unsafe PyYAML usage
Quick fix
PYSEC-2026-1313 — docling-core: upgrade to the fixed version with the command below.
pip install --upgrade 'docling-core>=2.48.4'Details
### 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 `docling_core.types.doc.DoclingDocument.load_from_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.
