提出 #768226: Jcharis Machine-Learning-Web-Apps <=1.0.0 Reflected XSS情報

タイトルJcharis Machine-Learning-Web-Apps <=1.0.0 Reflected XSS
説明The POST /preview endpoint takes user input from request.form['newtext'] and passes it directly to render_template() as a template variable. If the Jinja2 template renders newtext without escaping (e.g. using {{ newtext | safe }}), arbitrary HTML/JavaScript is injected into the response. The POC submits <img src=1 onerror=alert(9)> and the payload executes in the browser, confirming Reflected XSS. An attacker can craft a malicious link to steal session cookies or perform actions on behalf of the victim.
