HighCVSS 8.1
Published: Translated: NVD NIST

Summary

Coolify through 4.3.17 contains an authentication bypass vulnerability in the OAuth callback handler that signs users into existing accounts based solely on email address without verifying provider assertions or binding OAuth identities. Attackers can register a victim's email address on any enabled OAuth provider to obtain authenticated sessions as that user, bypassing password requirements and two-factor authentication.

Risk Assessment

The risk includes account takeover without knowledge of passwords, potentially leading to unauthorized access to data and administrative functions.

Recommendation

It is recommended to immediately update Coolify to a patched version and implement OAuth identity verification and account binding.
