CVE-2026-34171Public exploitNetwork attack vector

Account takeover via CSRF-triggered password reset

Published Jul 7, 2026 · Updated Jul 7, 2026

Cross-site request forgery in Coolify before 4.0.0-beta.471 allows remote authenticated users to take over accounts via an invitation link. The acceptInvitation() controller handles a state-changing GET parameter without CSRF protection and hashes the invitation UUID into the victim's password. A team admin or owner must create the invitation, and the logged-in victim must follow the crafted URL; the attacker then signs in with the known UUID and gains the victim's Coolify access.
