CVE-2026-81648
CryptoPayment Gateway 1.2.1 - 1.2.2 - Unauthenticated Arbitrary File Deletion and Settings Update via Unguarded AJAX Router
What happened?
The CryptoPayment Gateway WordPress plugin from 1.2.1 to 1.2.2 does not apply an authorization check on one of its AJAX endpoints, allowing unauthenticated users to invoke administrative operations, including deleting arbitrary files on the server, overwriting the payment gateway configuration and recovering stored wallet credentials in cleartext.
