Description
wpDiscuz before 7.6.47 contains a cross-site scripting vulnerability in the customCss field that allows administrators to inject malicious scripts by breaking out of style tags. Attackers with admin access can inject payloads like </style><script>alert(1)</script> in the custom CSS setting to execute arbitrary JavaScript in user browsers.
