Unauthenticated code execution via payment hook overwrite
Published Apr 16, 2026 · Updated Apr 16, 2026
Remote code execution in goodoneuz pay-uz 2.2.24 and earlier allows remote attackers to execute PHP through an unauthenticated endpoint. ApiController::file_put passes request-controlled content to file_put_contents, overwriting payment hook files that PaymentService later loads with require. The route has only web middleware by default, so no credentials or payment secret are required and successful requests execute code in the Laravel application.
