CVE-2026-109381 Details
Description
The Mage Eventpress plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 5.7.8 This is due to the mep_grant_shop_manager_access() function hooking user_has_cap and unconditionally granting manage_options whenever an attacker-controllable request marker matches — most notably $_GET['page'] starting with 'mep_' or 'mpwem_', which is never validated against an actually registered EventPress screen. This makes it possible for authenticated attackers, with Shop Manager-level access and above, to elevate their privileges to Administrator by appending ?page=mep_x to core admin URLs (options-general.
A privilege escalation vulnerability has been identified in the Mage Eventpress plugin for WordPress, affecting versions through 5.7.8. The issue arises from the mep_grant_shop_manager_access() function, which hooks into user capabilities and improperly grants 'manage_options' to users with Shop Manager access. This vulnerability can be exploited by appending specific page parameters to admin URLs, allowing authenticated attackers to elevate their privileges to Administrator.
Users are advised to update the Mage Eventpress plugin to version 5.7.9 or later.
