| 标题 | Jcharis Machine-Learning-Web-Apps <=1.0.0 Reflected XSS |
|---|
| 描述 | 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. |
