Summary

Sanluan PublicCMS 5 contains an authorization bypass in the TradePaymentService.pendingRefund function. The function trusts the userId argument, which the user controls, so the authorization check can be bypassed (CWE-639). A remote attacker with low privileges can exploit this without user interaction. A public exploit is available and might be used.
