Internal data disclosure via unvalidated preview URL

Published Sep 22, 2026 · Updated Sep 22, 2026

SSRF in changedetection.io 50389b07 allows remote attackers to read internal web content through the preview endpoint. The add_watch_ui_snapshot handler accepted any HTTP(S) url parameter and sent it to the configured server-side browser without private-address validation. When optional login is disabled, the preview route is unauthenticated and returns a screenshot, element data, and rendered page content.
