A cross-site scripting (XSS) vulnerability has been identified in Yifang CMS versions through 2.0.5. The issue resides in the 'store' function of the 'plugins/yifang_backend_account/logic/admin/L_rbac_admin.php' file, within the Extended Management Module. This vulnerability allows for stored XSS, as the 'account' parameter is directly saved to the database without proper sanitization. The flaw can be exploited remotely, and a public proof-of-concept exploit is available.
