CVE-2025-32778Public exploitNetwork attack vector

Unauthenticated command execution via screenshot URL

Published Apr 15, 2025 · Updated Apr 15, 2025

OS command injection in Alicia Sykes Web-Check before 2.0.1 allows remote attackers to execute arbitrary host commands via a crafted screenshot URL. The directChromiumScreenshot function in api/screenshot.js interpolates the url parameter into an exec() shell command without validation or escaping. The screenshot API is network-accessible without authentication, and successful exploitation grants the Web-Check process's host privileges.
