Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The GET /api/v1/deployments/{uuid} endpoint in Coolify prior to 4.0.0-beta.464 has an IDOR vulnerability where the teamId extracted from the authentication token is not used to scope the database query, allowing any authenticated user to view deployment details belonging to any team.

MitigationUpgrade Coolify to version 4.0.0-beta.464 or later. If immediate upgrade is not feasible, implement network-level access controls restricting API access to authorized team members only.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Coolify installation
    Check for Coolify by looking for its web interface (typically on port 8000) or by running 'docker ps' to see coolify containers
    Affected if Coolify is running and accessible via network
  2. Determine installed version
    Check the Coolify web interface footer for version number, or run 'docker ps' and inspect the coolify container image tag
    Affected if Version is displayed as anything prior to 4.0.0-beta.464 (e.g., 4.0.0-beta.463, 4.0.0-beta.400, etc.)
  3. Verify API endpoint is accessible
    Attempt to reach GET /api/v1/deployments/{uuid} endpoint using curl or similar: curl -k https://your-coolify-host/api/v1/deployments/any-uuid -H 'Authorization: Bearer YOUR_TOKEN'
    Affected if API returns HTTP 200 or 404 (rather than 401/403), indicating the endpoint exists and accepts authenticated requests
  4. Check authentication is enforced but not team-scoped
    Log in as a regular user belonging to Team A, then attempt to access a deployment UUID that belongs to Team B; observe if deployment details are returned without authorization error
    Affected if Request succeeds and returns deployment data belonging to a different team, indicating the teamId is not being used to scope the query

User is affected if running Coolify version earlier than 4.0.0-beta.464 and the API endpoint is accessible to authenticated users who should not have cross-team visibility.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Coolify to version 4.0.0-beta.464 or later. If immediate upgrade is not feasible, implement network-level access controls restricting API access to authorized team members only.

Recommended fix High confidence

4.0.0-beta.464

  1. Upgrade Coolify to version 4.0.0-beta.464 or later to address the IDOR vulnerability in the /api/v1/deployments/{uuid} endpoint
  2. Verify that the team-based authorization is now properly enforced by testing access to deployment resources across different teams
