{"cve":"CVE-2026-75983","nvd":{"published":"2026-09-15T07:16:29.743","modified":"2026-09-15T15:17:21.443","status":"Deferred","description":"The Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.1.23. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.5},"cwes":["CWE-269"],"references":["https://plugins.trac.wordpress.org/browser/wp-event-solution/tags/4.1.21/core/AccessControl/PermissionManager.php#L24","https://plugins.trac.wordpress.org/browser/wp-event-solution/tags/4.1.21/core/AccessControl/PermissionManager.php#L52","https://plugins.trac.wordpress.org/browser/wp-event-solution/tags/4.1.21/core/Admin/AdminProvider.php#L32","https://plugins.trac.wordpress.org/changeset?reponame=&old=3689867%40wp-event-solution&new=3689867%40wp-event-solution","https://www.wordfence.com/threat-intel/vulnerabilities/id/ff48db43-9cfa-4dab-b25e-bbc211121f6c?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-75983","score":0.00705,"percentile":0.53351,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
