Summary
Coolify prior to version 4.0.0-beta.464 has a vulnerability in the `GET /api/v1/servers/{server_uuid}/domains?uuid={app_uuid}` endpoint that bypasses team scoping when the optional `uuid` parameter is provided. Any authenticated API user can enumerate domain names (FQDNs) of applications belonging to other teams.
Risk Assessment
The risk involves unauthorized disclosure of domain names of other teams' applications, potentially leading to information leakage about infrastructure and subsequent attacks on those applications.
Recommendation
Immediately update Coolify to version 4.0.0-beta.464 or later, which includes a fix for this vulnerability.
