Authentication Bypass in DevKit Pro (WordPress plugin) (CVE-2026-14378)
Summary
Authentication bypass in DevKit Pro (WordPress plugin) (CVE-2026-14378). Successful exploitation can lead to full system takeover. Exploitable via revert_switch.
Original description
The description as published by the source.
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.
