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.
