Doc Text:
A flaw was found in docling. This vulnerability can lead to information disclosure when HTML page rendering is enabled. The document rendering backend fails to enforce local file access restrictions or confine requests to the source document directory. An attacker could exploit this issue by submitting a crafted HTML file, causing sensitive local files to be embedded and exposed in browser-rendered page images.

Description OSIDB Bzimport 2026-10-05 21:52:20 UTC 
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.
