Overview

docling is a 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 Server-side Request Forgery (SSRF) in the HTML rendering process when the HTML backend is explicitly configured for rendering. An attacker can execute arbitrary JavaScript and perform unauthorized network requests by submitting malicious Playwright HTML documents.

Workaround

This vulnerability can be mitigated by refraining from using render_page=True.
