Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

CryptoPayment Gateway versions 1.2.1 through 1.2.2 are affected. The plugin's AJAX endpoint lacks an authorization check, so an unauthenticated remote attacker can run administrative operations. These include deleting arbitrary files on the server, overwriting the payment gateway configuration, and retrieving stored wallet credentials in cleartext. The source gives no fixed version and no workaround.
