Doc Text:	A flaw was found in Docling. If the HTML backend is explicitly configured for rendering, a remote attacker could exploit a vulnerability in the Playwright-based rendering feature by crafting malicious HTML documents. This could allow the attacker to execute arbitrary JavaScript or make unauthorized network requests, potentially leading to Server-Side Request Forgery (SSRF) attacks, data exfiltration, or remote code execution.

Description OSIDB Bzimport 2026-06-24 18:06:40 UTC

Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. FIn versions >= 2.82.0, < 2.91.0, if the HTML backend was explicitly configured for rendering (rendering option by default deactivated), then the Playwright-based rendering feature could allow JavaScript execution and unrestricted network access when processing untrusted HTML documents. An attacker could craft malicious HTML that executes arbitrary JavaScript in the rendering context or makes unauthorized network requests to internal services, potentially leading to SSRF attacks, data exfiltration, or remote code execution in the rendering environment. This vulnerability is fixed in 2.91.0.
