CVE-2025-69206Public exploitNetwork attack vector

Authenticated blind SSRF via hostname-only webhook validation

Published Dec 29, 2025 · Updated Dec 29, 2025

Server-side request forgery in Hemmelig.app before 7.3.3 allows remote authenticated users to probe internal services via webhook URLs. The Secret Requests isPublicUrl function compares only the submitted hostname against private-address patterns, without resolving DNS, while webhook fetches follow redirects. An account and a crafted webhook URL are required; the blind request exposes port reachability through timing or connection behavior but does not return response bodies.
