This is due to the `PermissionManager::manage_permissions()` function being registered as a callback on WordPress core's `map_meta_cap` filter and unconditionally returning the always-true `'exist'` primitive for every capability check whenever the evaluated user ID is 1, without scoping this behavior to plugin-specific capabilities. This makes it possible for authenticated attackers whose account is user ID 1, even subscribers, to pass every WordPress capability check, including `manage_options`, `edit_plugins`, `edit_themes`, `promote_users`, and `update_core`, thereby elevating their privileges to administrator-equivalent power and achieving full site takeover, including remote code execution via the plugin and theme editors. Exploitation is only impactful when user ID 1 has been deliberately demoted to a lower-privilege role as a common administrator-account hardening practice; on default installations where user ID 1 retains the administrator role, no incremental privilege gain occurs."}],"title":"Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce <= 4.1.23 - Authenticated (Subscriber+) Privilege Escalation via map_meta_cap Filter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/ff48db43-9cfa-4dab-b25e-bbc211121f6c?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wp-event-solution/tags/4.1.21/core/AccessControl/PermissionManager.php#L52"},{"url":"https://plugins.trac.wordpress.org/browser/wp-event-solution/tags/4.1.21/core/AccessControl/PermissionManager.php#L24"},{"url":"https://plugins.trac.wordpress.org/browser/wp-event-solution/tags/4.1.21/core/Admin/AdminProvider.php#L32"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3689867%40wp-event-solution&new=3689867%40wp-event-solution"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-269 Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":7.5,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Wordfence PRISM"}],"timeline":[{"time":"2026-08-18T18:42:21.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-09-14T17:13:14.000Z","lang":"en","value":"Disclosed"}]}}}
