AnalysisAI

Technical ContextAI
The vulnerability is a stored XSS (CWE-79) in the Login/Signup Popup WordPress plugin (slug: easy-login-woocommerce). The plugin provides customizable popup forms for login and registration. The flaw occurs when user-supplied input is not properly sanitized before being stored and later rendered in web pages, allowing script injection.
