{"cve":"CVE-2026-24009","nvd":{"published":"2026-01-22T16:16:09.320","modified":"2026-06-17T10:22:28.303","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-502"],"references":["https://github.com/advisories/GHSA-8q59-q68h-6hv4","https://github.com/docling-project/docling-core/commit/3e8d628eeeae50f0f8f239c8c7fea773d065d80c","https://github.com/docling-project/docling-core/issues/482","https://github.com/docling-project/docling-core/releases/tag/v2.48.4","https://github.com/docling-project/docling-core/security/advisories/GHSA-vqxf-v2gg-x3hc"],"products":["docling:docling-core"],"source":"nvd","synced_at":"2026-10-19T22:21:16.563232421+00:00"},"epss":{"cve":"CVE-2026-24009","score":0.01534,"percentile":0.74824,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-vqxf-v2gg-x3hc","url":"https://osv.dev/vulnerability/GHSA-vqxf-v2gg-x3hc","summary":"docling-core vulnerable to Remote Code Execution via unsafe PyYAML usage","modified":"2026-07-07T17:56:50.418251461Z","packages":[{"ecosystem":"PyPI","name":"docling-core","purl":"pkg:pypi/docling-core","ranges":[">=2.21.0 <2.48.4"],"fixed":["2.48.4"]}]},{"id":"PYSEC-2026-1313","url":"https://osv.dev/vulnerability/PYSEC-2026-1313","summary":"docling-core vulnerable to Remote Code Execution via unsafe PyYAML usage","modified":"2026-07-07T17:46:38.921284013Z","packages":[{"ecosystem":"PyPI","name":"docling-core","purl":"pkg:pypi/docling-core","ranges":[">=2.21.0 <2.48.4"],"fixed":["2.48.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
