The vulnerability exists because the `update_cc_details()` AJAX handler forwards an attacker-supplied `username` parameter to ONTRAPORT via `api_call('update_cc_details', ...)` before performing the local `username_exists()` collision check, and aborts without rolling back the remote rename when a collision is detected — leaving the remote ONTRAPORT contact renamed to an existing WordPress Administrator's login. On a subsequent login attempt, `user_login()` (hooked to `wp_authenticate`) authenticates against ONTRAPORT using the renamed login and the attacker's own password, resolves the local WordPress user row via `get_user_by('login', $username)` — which now selects the real Administrator's row — and calls `wp_set_password()` against that Administrator's user ID; because the `user_level != 10` guard only suppresses PilotPress's own cookie issuance rather than returning a `WP_Error` to core, WordPress proceeds to validate the newly-synchronized password and issues a full Administrator authentication cookie to the attacker. This makes it possible for authenticated attackers with Subscriber-level access and above — specifically any PilotPress member holding a valid ONTRAPORT contact and the Customer Center nonce — to fully take over an Administrator account.\n\n## Affected\n\n- `PilotPress <= 2.0.43`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
