This makes it possible for authenticated attackers with Subscriber-level access or above to restore the stale stored Administrator role to their own account, effectively escalating their privileges to Administrator. Exploitation requires that the attacker's account previously held the Administrator role and used the View Admin Role Switcher feature before being demoted specifically through the bulk role-change control rather than the Edit User screen, as only the bulk path bypasses the `profile_update` hook that would otherwise have cleared the stored original role.","state":0,"publishedAt":"2026-10-16T04:27:03.097+00:00","modifiedAt":"2026-10-16T16:04:40.422+00:00","affected":[{"ecosystem":"Vendor product","name":"Nexter Extension – Security, Performance, Code Snippets & Site Toolkit","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"posimyththemes\",\n                    \"product\": \"Nexter Extension – Security, Performance, Code Snippets & Site Toolkit\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"4.7.11\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/ae86441d-5a95-45a7-869a-9e7872365a1f?source=cve","https://plugins.trac.wordpress.org/browser/nexter-extension/tags/4.7.11/include/panel-settings/extensions/nexter-ext-view-admin-role.php#L287","https://plugins.trac.wordpress.org/browser/nexter-extension/tags/4.7.11/include/panel-settings/extensions/nexter-ext-view-admin-role.php#L265","https://plugins.trac.wordpress.org/browser/nexter-extension/tags/4.7.11/include/panel-settings/extensions/nexter-ext-view-admin-role.php#L51","https://plugins.trac.wordpress.org/browser/nexter-extension/tags/4.7.11/include/panel-settings/extensions/nexter-ext-view-admin-role.php#L302","https://plugins.trac.wordpress.org/changeset/3740891/nexter-extension/trunk/include/panel-settings/extensions/nexter-ext-view-admin-role.php"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-111114","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-111114","identifiers":["CVE-2026-111114"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
