CVE-2026-44016Network attack vector

Code execution and SSRF via unsafe HTML rendering

Published Jun 24, 2026 · Updated Jun 24, 2026

Code injection and SSRF in Docling 2.82.0 and later before 2.91.0 allow remote attackers to exploit rendering via crafted HTML documents. The HTML backend launches a Playwright browser with JavaScript enabled and unrestricted network access when render_page is set, so hostile markup can execute scripts and reach internal services. Rendering is disabled by default, and exploitation requires an application or user to process untrusted HTML with render_page enabled; consequences include SSRF, data exfiltration, and code execution in the rendering context.
