CVE-2026-27883: 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, 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.
AI Analysis
Technical Summary
CVE-2026-27883 is an authorization bypass vulnerability in coollabsio's Coolify product affecting versions before 4.0.0-beta.464. The GET /api/v1/deployments/{uuid} endpoint improperly authorizes access by not scoping deployment data queries to the team ID extracted from the authentication token. As a result, any authenticated user can retrieve deployment details belonging to other teams. The vulnerability is classified under CWE-639 (Authorization Bypass Through User-Controlled Key). The issue is resolved in version 4.0.0-beta.464.
Potential Impact
An authenticated user can access deployment information from any team, potentially exposing sensitive deployment details across team boundaries. The vulnerability does not allow modification or denial of service but leaks information that should be restricted by team-based authorization.
Mitigation Recommendations
Upgrade to version 4.0.0-beta.464 or later, where the authorization bypass vulnerability is fixed. Patch status is not explicitly confirmed in the vendor advisory, but the description states the issue is fixed starting from 4.0.0-beta.464. Until upgrading, restrict access to trusted users only and monitor for unauthorized access attempts.
