CVE-2026-34171
HIGH 8 PoC AVAILABLECoolify 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.
Public exploit or PoC code exists. Modeled probability is still low, but the barrier to attack is reduced — watch closely.
