CVE-2024-23329Public exploitNetwork attack vector

Watch-history disclosure via missing API token check

Published Jan 19, 2024 · Updated Nov 13, 2024

Incorrect authorization in changedetection.io 0.39.14 through 0.45.12 allows remote attackers to read watch-history paths by UUID. The WatchHistory.get handler returns watch.history without the auth.check_token decorator that protects API requests. No credentials or user interaction are required, but an attacker must know a watch UUID; only server-side snapshot paths are disclosed.
