CWE-269 — Improper Privilege Management

This CVE was published Apr 27, 2026 and is one of 1 known issue for this plugin.

What to do

Update, patch or deactivate.

The official author release notes confirm remediation by 1.0.1; this does not establish that every intervening release was affected. Update the affected edition to 1.0.5 or a later maintained release on its supported branch. The recommended 1.0.5 release incorporates later related fixes or hardening. The earlier author-attributed remediation remains 1.0.1; recommending a later release does not by itself prove the earlier fix failed. Official author release notes: https://wordpress.org/plugins/highland-software-custom-role-manager/.

A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical 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.
