The package uses multi-character tokens, and each replacement is applied only once. When one occurrence is removed, it can create another dangerous token due to overlap. This means that even the &#8220;sanitized&#8221; values may still contain an executable payload when used in href\/src, or if injected into the DOM.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2527708870\" 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 is a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request:<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/vulnerable_page HTTP\/1.1\nHost: target.example.com\nContent-Type: text\/html\n&lt;a href=&quot;javasjavascript:cript:malicious_code();&quot;&gt;Click me&lt;\/a&gt;<\/code><\/pre>\n<p>In this example, the regex blacklist sanitization would remove the first occurrence of &#8220;javascript:&#8221;, leaving the second one intact and ready to execute the malicious_code() when a user interacts with the link.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>Currently, there is no vendor-supplied fix for this issue. As a temporary measure, it is recommended to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to mitigate potential attacks.
