CVE-2026-27956

Full vulnerability record from the local CVENow database.

Description

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, `GET /api/v1/servers/{server_uuid}/domains?uuid={app_uuid}` bypasses team scoping when the optional uuid query parameter is provided. Any authenticated API user can enumerate domain names (FQDNs) of applications belonging to other teams. This vulnerability is fixed in 4.0.0-beta.464.
