{"id":"PYSEC-2026-2456","summary":"Docling Core: Insufficient validation of image reference URIs","details":"### Impact\nIn versions `\u003e= 2.5.0, \u003c 2.74.1`, `docling-core`  could allow local `file://` image references and accepted inline `data:` content without a decoded-size limit.\n\nIn applications that accept untrusted image references, this may allow access to local files readable by the process or excessive memory use from large inline payloads.\n\n### Patches\nPatched in `docling-core` `2.74.1`.\nThe fix blocks local file URIs by default and adds a size limit for decoded inline image data.\n\nUsers should upgrade to:\n- `docling-core` `\u003e= 2.74.1`\n\n### Workarounds\nIf upgrading is not immediately possible:\n- reject `file:` and `data:` image references from untrusted input\n- allow only approved local or remote image sources\n- apply input size and memory limits to processing workers\n\n### References\n- Fix release: [`v2.74.1`](https://github.com/docling-project/docling-core/releases/tag/v2.74.1)","aliases":["CVE-2026-44019","GHSA-j5xp-7m2f-49jv"],"modified":"2026-07-13T16:31:39.985553936Z","published":"2026-07-13T15:46:14.500928Z","references":[{"type":"WEB","url":"https://github.com/docling-project/docling-core/security/advisories/GHSA-j5xp-7m2f-49jv"},{"type":"PACKAGE","url":"https://github.com/docling-project/docling-core"},{"type":"WEB","url":"https://github.com/docling-project/docling-core/releases/tag/v2.74.1"},{"type":"PACKAGE","url":"https://pypi.org/project/docling-core"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-j5xp-7m2f-49jv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44019"}],"affected":[{"package":{"name":"docling-core","ecosystem":"PyPI","purl":"pkg:pypi/docling-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.5.0"},{"fixed":"2.74.1"}]}],"versions":["2.10.0","2.11.0","2.12.0","2.12.1","2.13.0","2.13.1","2.14.0","2.15.0","2.15.1","2.16.0","2.16.1","2.17.0","2.17.1","2.17.2","2.18.0","2.18.1","2.19.0","2.19.1","2.20.0","2.21.0","2.21.1","2.21.2","2.22.0","2.23.0","2.23.1","2.23.2","2.23.3","2.24.0","2.24.1","2.25.0","2.26.0","2.26.1","2.26.2","2.26.3","2.26.4","2.27.0","2.28.0","2.28.1","2.29.0","2.30.0","2.30.1","2.31.0","2.31.1","2.31.2","2.32.0","2.33.0","2.33.1","2.34.0","2.34.1","2.34.2","2.35.0","2.36.0","2.37.0","2.38.0","2.38.1","2.38.2","2.39.0","2.40.0","2.41.0","2.42.0","2.43.0","2.43.1","2.44.0","2.44.1","2.44.2","2.45.0","2.46.0","2.47.0","2.48.0","2.48.1","2.48.2","2.48.3","2.48.4","2.49.0","2.5.0","2.5.1","2.50.0","2.50.1","2.51.0","2.51.1","2.52.0","2.53.0","2.54.0","2.54.1","2.55.0","2.56.0","2.57.0","2.58.0","2.58.1","2.59.0","2.6.0","2.6.1","2.60.0","2.60.1","2.60.2","2.61.0","2.62.0","2.63.0","2.64.0","2.65.0","2.65.1","2.65.2","2.66.0","2.67.0","2.67.1","2.68.0","2.69.0","2.7.0","2.7.1","2.70.0","2.70.1","2.70.2","2.71.0","2.72.0","2.73.0","2.74.0","2.8.0","2.9.0"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/docling-core/PYSEC-2026-2456.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H"}]}
