GHSA-wr6w-jxg7-qpfh: Jenkins Missing Permission Check
Jenkins 2.503 and earlier, LTS 2.492.2 and earlier does not perform a permission check in an HTTP endpoint.
This allows attackers with Computer/Create permission but without Computer/Configure permission to copy an agent, gaining access to encrypted secrets in its configuration.
This is due to an incomplete fix of SECURITY-3495/CVE-2025-27622.
Jenkins 2.504, LTS 2.492.3 requires Computer/Configure permission to copy an agent containing secrets.
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.
