Software

Affected versions

< 4.0.0-beta.374

Patched versions

v4.0.0-beta.471

Description

Summary

Coolify server and project lookups are not scoped to the current team, allowing any authenticated user to access servers and projects belonging to other teams by specifying their IDs directly.

Impact

  • Cross-team data access: Users can view and potentially modify servers and projects belonging to other teams
  • Horizontal privilege escalation: Any authenticated user can access resources outside their authorized team scope

Remediation

Scope all server and project queries to the current user's team. Add team-level authorization checks on all resource lookup endpoints.

Note: This advisory has been assigned CVE-2026-34592 and the submission has been accepted. Ready for publication.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Authorization Bypass Through User-Controlled Key

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. Learn more on MITRE.
