A privilege escalation flaw in Sonaar enables low-privileged subscriber accounts to perform unauthorized actions, potentially leading to full site compromise.

This vulnerability involves improper capability checking within the Sonaar plugin. It allows users with "Subscriber" level access to escalate their privileges to perform administrative tasks.

Exploitation of this vulnerability allows unauthorized users to gain elevated access, potentially leading to data modification, site configuration changes, or the installation of malicious software. With a CVSS score of 8.8, this represents a significant security risk, as it bypasses the principle of least privilege within the WordPress environment.

Immediate Action: Update the Sonaar plugin to the most recent version provided by the vendor to enforce correct capability checks.

Proactive Monitoring: Audit user activity logs to identify any accounts performing actions outside their assigned roles or permissions.

Compensating Controls: Implement strict role-based access control (RBAC) and restrict the registration of new user accounts until the patch is applied.

Public Exploit Available: false

Organizations should audit their current user base and immediately apply the vendor-supplied update to the Sonaar plugin. Ensuring that only authorized users maintain elevated privileges is essential to maintaining the integrity of the application.
