Not Vulnerable:

Plone 'safe_html' HTML Injection Vulnerability

Plone 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.

All versions since Plone 2.1 are vulnerable.
