The Membership & User Roles for WooCommerce (Automatic Role Changer) plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 20260828. This is due to the function unconditionally re-assigning every role stored in the user meta cache without verifying that each cached role is still actively assigned by the external provider — a condition made permanent by , which merges new foreign roles into the cache but never evicts roles that have since been revoked. This makes it possible for authenticated attackers with subscriber-level access and above to restore a previously revoked Administrator role to their own account, gaining full administrative control of the site, by triggering any role-assignment event such as completing a purchase for a role-mapped product. Exploitation requires Replace Roles mode to be enabled and the attacker's account to have previously received Administrator legitimately through a separate role-management mechanism while the plugin was active, so that was written into the user meta cache before the external provider revoked it.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
