{"id":"CVE-2026-24009","aliases":["GHSA-vqxf-v2gg-x3hc","PYSEC-2026-1313"],"url":"https://o3.security/vulnerability/CVE-2026-24009","summary":"Docling Core vulnerable to Remote Code Execution via unsafe PyYAML usage","details":"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.","published":"2026-01-22T15:04:52.745Z","modified":"2026-08-07T11:49:52.316719275Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"docling-core","fixedVersion":"2.48.4"}],"fix":{"url":"https://github.com/docling-project/docling-core/commit/3e8d628eeeae50f0f8f239c8c7fea773d065d80c","label":"docling-project/docling-core@3e8d628"},"references":[{"type":"WEB","url":"https://github.com/docling-project/docling-core/releases/tag/v2.48.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24009.json"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-8q59-q68h-6hv4"},{"type":"ADVISORY","url":"https://github.com/docling-project/docling-core/security/advisories/GHSA-vqxf-v2gg-x3hc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24009"},{"type":"REPORT","url":"https://github.com/docling-project/docling-core/issues/482"},{"type":"FIX","url":"https://github.com/docling-project/docling-core/commit/3e8d628eeeae50f0f8f239c8c7fea773d065d80c"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:49:52.316719275Z"}}
