{"schemaVersion":3,"id":"CVE-2026-75983","aliases":[],"status":"published","duplicateOf":null,"title":null,"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.","dates":{"published":"2026-09-15T06:07:31.947Z","modified":"2026-09-15T14:10:24.241Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"wordfence","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00705,"percentile":0.52515,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.294,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00411},"history":[{"date":"2026-09-15T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00705,"percentile":0.52515}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00411,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00705,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00705,
