CVE-2026-34171

HIGH 8 PoC AVAILABLE

Published 2026-07-07 · Last modified 2026-07-07

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, the GET /invitations/{uuid} endpoint can perform a state-changing password reset using an attacker-known invitation UUID, allowing an attacker who can cause a victim to visit the crafted invitation URL to reset the victim account password to a predictable value. This issue is fixed in version 4.0.0-beta.471.
