Technical details
The vulnerability is a privilege escalation (CWE-269) affecting the plugin's role and capability management functionality. The plugin fails to enforce proper authorization checks when updating role capabilities, allowing users holding the vendor role to grant themselves administrator-level permissions. Exploitation requires authentication as a vendor-role user, but no additional user interaction is needed. An authenticated vendor can directly call the affected functionality to add administrative capabilities to their role, resulting in full site compromise. Fixed in version 5.0.16.
