Detailsinfo

A vulnerability, which was classified as problematic, has been found in docling-project Docling up to 2.120.2. Affected by this issue is the function _image_ref_from_odf_image of the file docling/backend/opendocument_backend.py of the component OpenDocument Backend. The manipulation of the argument enable_local_fetch with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality. CVE summarizes:

Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. From 2.107.0 until 2.120.3, docling/backend/opendocument_backend.py uses the xlink:href attribute value of a draw:image element as a filesystem path when the referenced part is not found in the document archive. The _image_ref_from_odf_image function reads that attacker-controlled path without a scheme check, extraction-directory confinement, or the enable_local_fetch setting used by other backends. Readable files that Pillow can decode as images are embedded in converted output, and other existing paths can be distinguished through the attempted read. This issue is fixed in 2.120.3.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-105751 since 10/05/2026. The exploitation is known to be easy. The attack may be launched remotely.
