CVE-2026-27956: CWE-639: Authorization Bypass Through User-Controlled Key in coollabsio coolify
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.
AI Analysis
Technical Summary
CVE-2026-27956 is an authorization bypass vulnerability (CWE-639) in coollabsio's Coolify product. Specifically, before version 4.0.0-beta.464, the GET /api/v1/servers/{server_uuid}/domains endpoint improperly handles the optional uuid query parameter, allowing authenticated users to bypass team scoping controls and enumerate fully qualified domain names (FQDNs) of applications owned by other teams. This exposure of domain information could lead to information disclosure. The vulnerability is resolved in version 4.0.0-beta.464.
Potential Impact
The vulnerability allows authenticated API users to access domain names of applications outside their authorized team scope, resulting in unauthorized information disclosure of application domain names. There is no indication of impact on integrity or availability.
Mitigation Recommendations
Upgrade to version 4.0.0-beta.464 or later, where this authorization bypass issue is fixed. Patch status is not explicitly stated but the fix is included in 4.0.0-beta.464. Until upgraded, restrict API access to trusted users only.
