TextPattern Comment HTML Injection Vulnerability

TextPattern is prone to an HTML-injection vulnerability because it fails to properly sanitize user-supplied input before using it in dynamically generated content.

Successful exploits will allow attacker-supplied HTML and script code to run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.

TextPattern 4.2.0 is vulnerable; others versions may also be affected.
