CVSS 8.8 · HIGH

CVE-2026-7106

The Highland Software Custom Role Manager plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 1.0.0. This is due to insufficient authorization checks in the hscrm_save_user_roles() function, which is hooked to the personal_options_update action accessible by any authenticated user. This makes it possible for authenticated attackers, with Subscriber-level access or higher, to potentially modify user roles via the profile update form.
