Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, the "GET /api/v1/deployments/{uuid}" endpoint allows any authenticated user to access deployment details belonging to any team, bypassing team-based authorization. The $teamId is extracted from the authentication token but never used to scope the database query. This vulnerability is fixed in 4.0.0-beta.464.
