CVE-2026-7106
CWE-269Published: April 27, 2026· Updated: Apr 27, 2026
Official Description
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.
Technical Analysis
CVE-2026-7106 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
