Upgrade docling-slim to version 2.131.0 or higher.
Overview
docling-slim is a Modular version of the Docling package: SDK and CLI for parsing PDF, DOCX, HTML, and more, to a unified document representation for powering downstream workflows such as gen AI applications.
Affected versions of this package are vulnerable to External Control of File Name or Path via the DoclingJSONBackend when processing a DoclingDocument JSON input containing ImageRef fields with local filesystem paths or file:// URIs. An attacker who can supply a malicious JSON document can cause the converter to open arbitrary local files on the host, which are then read by enrichment models or embedded-image export stages, exposing their contents.
Note: This is only exploitable when the application accepts InputFormat.JSON_DOCLING input, which is enabled by default.
