CVE-2024-51998Public exploitNetwork attack vector

Unauthenticated local file read via file URI bypass

Published Nov 7, 2024 · Updated Nov 8, 2024

Path traversal in dgtlmoon changedetection.io 0.47.05 and earlier allows remote attackers to read local files via a crafted file URI. The WebDriver processor rejects URLs beginning with file://, but is_safe_url also accepts valid file:/ URLs, so that form bypasses the ALLOW_FILE_URI=false guard. Exploitation requires a WebDriver-enabled instance and exposes files readable by the application process without authentication.
