DescriptionCVE.org

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.

AnalysisAI

Authenticated users can access deployment details of any team in Coolify prior to version 4.0.0-beta.464, bypassing team-based authorization. The vulnerability exposes sensitive deployment configuration and metadata, requiring only low-privilege authentication and no user interaction. A public proof-of-concept exists, but EPSS indicates a low probability of widespread exploitation (0.21%).
