Summary

The Event Booking Manager for WooCommerce plugin by magepeopleteam is vulnerable to privilege escalation in versions up to and including 5.7.8. The mep_grant_shop_manager_access() function hooks user_has_cap and grants manage_options whenever an attacker-controllable request marker matches, such as $_GET['page'] starting with 'mep_' or 'mpwem_', without checking that the screen is registered. An authenticated attacker with Shop Manager access or higher can append ?page=mep_x to core admin URLs such as options-general.php to gain Administrator privileges, which is classified as CWE-269, Improper Privilege Management, with a CVSS 3.1 base score of 7.2 (HIGH).

Description from the CNA

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.
