{"cve":"CVE-2026-111114","nvd":{"published":"2026-10-16T05:17:30.350","modified":"2026-10-16T16:17:04.080","status":"Deferred","description":"The Nexter Extension – Security, Performance, Code Snippets & Site Toolkit plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.7.11 The vulnerability exists because the `/?reset-view` handler in `role_switcher_to_view_admin_as()` performs no nonce or capability check when the supplied username matches the authenticated caller, and because the plugin's only cleanup mechanism — the `profile_update` hook — does not fire when WordPress performs a bulk role change via `wp-admin/users.php?action=promote`, which calls `WP_User::set_role()` directly and leaves a stale `administrator` value in the `nxtext_view_admin_original_role` user meta. 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.","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/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#L287","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/browser/nexter-extension/tags/4.7.11/include/panel-settings/extensions/nexter-ext-view-admin-role.php#L51","https://plugins.trac.wordpress.org/changeset/3740891/nexter-extension/trunk/include/panel-settings/extensions/nexter-ext-view-admin-role.php"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-111114","score":0.00281,"percentile":0.20367,"date":"2026-10-25"},"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).
