CVE-2025–59475: Jenkins Missing Permission Check Vulnerability

Jenkins is widely used for automating software development workflows, but even trusted platforms can contain security gaps. CVE-2025–59475 is a medium-severity vulnerability caused by a missing permission check in the authenticated user profile menu.

How the Vulnerability Works

The issue occurs when Jenkins fails to properly verify user permissions before displaying certain options in the profile dropdown menu. This could allow authenticated users without the required Overall/Read permission to discover limited information about the Jenkins configuration, such as installed plugins or available features.

Security Impact

Although the vulnerability does not directly allow privilege escalation, exposing internal configuration details can help attackers gather information about the environment and plan further attacks. Permission validation is a critical part of securing CI/CD platforms like Jenkins.

Mitigation

Organizations using affected Jenkins versions should:

• Upgrade to patched versions of Jenkins.
• Review user roles and access permissions.
• Follow least-privilege security practices.
• Regularly audit CI/CD environments for configuration exposure.

Conclusion

CVE-2025–59475 highlights the importance of enforcing proper authorization checks across every application component. Even minor information leaks can increase security risks when combined with other attack techniques.
