CVE-2026-85128: CWE-269 Improper Privilege Management in Choose User Role at Registration
The Choose User Role at Registration WordPress plugin before 1.3.3 does not validate the role requested at registration against the roles an administrator chose to offer, allowing unauthenticated users to request any role, including administrator, and to be granted it once the request is approved. Exploitation requires the Choose User Role at Registration WordPress plugin before 1.3.3's role selection feature and public account registration to both be enabled.
