Technical details

The vulnerability exists in the setHtml() method, which accepts HTML input without sanitizing or restricting file:// protocol URLs. Attackers can embed iframe, img, link, or script elements with root-relative paths (e.g., /etc/passwd) that resolve to file:// URLs when rendered by Chromium headless, exposing server file contents. This is a path traversal vulnerability requiring only the ability to control HTML input to the library; the attacker gains unauthorized file read access on the server.
