Vulnerability Title
Coolify: Cross-team deployment information disclosure via GET /api/v1/deployments/{uuid} (IDOR)
Source: CVE Program / CVE List V5
Vulnerability 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/deployments/{uuid}` in DeployController.php retrieves deployment details without validating that the deployment belongs to the authenticated user's team. Any authenticated API user can read deployment records from other teams by providing a valid deployment UUID. This vulnerability is fixed in 4.0.0-beta.464.
