Summary

Docling from 2.82.0 before 2.118.1 and docling-slim from 2.92.0 before 2.118.1 do not enforce the enable_local_fetch setting in HTML browser-rendering mode. The HTML backend permits file URLs, so local requests are not confined to the source document directory (CWE-552). An attacker who supplies crafted HTML as a filesystem path can embed a readable local text file in the rendered page image when Playwright is installed. Stream inputs, the default configuration and non-rendering backends are not affected.

Description from the CNA

Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. From 2.82.0 until 2.118.1, HTMLBackendOptions(render_page=True) permits file URLs because HTMLDocumentBackend._get_browser_request_block_reason does not enforce the enable_local_fetch setting or confine local requests to the source document directory. Crafted path-backed HTML can embed a readable local text file in a browser-rendered page image when Playwright is installed. Only filesystem Path inputs are affected because stream inputs use an opaque origin, and the default configuration, command-line interface, docling-serve, and non-rendering backends are not affected. This issue is fixed in 2.118.1.
