CVE-2026-14378

Critical

Description

The DevKit Pro plugin for WordPress is vulnerable to Authentication Bypass Leading to Administrator Account Takeover in all versions up to, and including, 2.3.0 This is due to the `revert_switch` handler trusting the attacker-controlled `original_user_id` cookie as the privileged identity: `verify_nonce_and_capability()` incorrectly checks the `manage_options` capability on the user identified by the cookie rather than on the actual requester via `current_user_can()`, while the switch-back form and a valid session-bound nonce are emitted publicly via `wp_footer` to any visitor — including unauthenticated users — whenever that cookie is present. This makes it possible for unauthenticated attackers to set the `original_user_id` cookie to any administrator's user ID, collect the rendered nonce, and POST it back to the `revert_switch` handler, causing `wp_set_auth_cookie()` to be called with the administrator's ID and granting the attacker a full administrator-level authenticated session and complete site takeover.
