Docling Core defines core data types and transformations for the document processing application Docling. In versions 1.5.0 and above, prior to 2.74.1, docling-core did not sufficiently restrict remote request destinations and could resolve a server-provided Content-Disposition to a local path in an unsafe manner. In applications that accept untrusted URLs, this could allow SSRF attacks targeting local files outside the user-defined cache directory. This issue has been fixed in version 2.74.1.

Docling Core defines core data types and transformations for the document processing application Docling. In versions 2.5.0 and above, prior to 2.74.1, docling-core could allow local file:// image references and accepted inline data: content without a decoded-size limit. In 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. This issue has been fixed in version 2.74.1.

Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. From 2.45.0 until 2.91.0, the METS-GBS backend's XML parsing and the input document format detection lacked security controls. An attacker could craft malicious METS-GBS archives that, when processed, could read sensitive files, exhaust system resources, or cause application crashes. This vulnerability is fixed in 2.91.0.

Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. Prior to 2.94.0, the HTML backend has unsafe URI and path handling. This vulnerability is fixed in 2.94.0.
