CVE-2026-19946

Description

The Awesome Support plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 6.3.9. This is due to a missing capability check on the wpas_do_mr_deny_user() function, which unlike its counterpart wpas_do_mr_activate_user() does not enforce current_user_can('edit_users') or current_user_can('edit_user', $user_id), relying solely on a nonce that is not scoped to the target user. This makes it possible for authenticated attackers, with subscriber-level access and above, to set the mr_user_denied flag on any user account — including administrators — permanently blocking their moderated activation and dispatching a denial notification email to the victim.
