docling-core vulnerable to Remote Code Execution via unsafe PyYAML usage

Open Source Vulnerabilities GHSA-vqxf-v2gg-x3hc

### 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. ### References * GitHub Issue: #482 * Upstream Advisory: CVE-2020-14343 * Fix Release: [v2.48.4](https://github.com/docling-project/docling-core/releases/tag/v2.48.4)

Open Source Vulnerabilities CVE-2026-24009

Docling Core (or docling-core) is a library that defines core data types and transformations in the document processing application Docling. A PyYAML-related Remote Code Execution (RCE) vulnerability, namely CVE-2020-14343, is exposed in docling-core starting in version 2.21.0 and prior to version 2.48.4, specifically only if the application uses pyyaml prior to version 5.4 and invokes `docling_core.types.doc.DoclingDocument.load_from_yaml()` passing it untrusted YAML data. 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. Users who cannot immediately upgrade docling-core can alternatively ensure that the installed version of PyYAML is 5.4 or greater.
