**Name of the Vulnerable Software and Affected Versions** TinyMCE version 3.5.8 **Description** The issue concerns the bbcode plugin in TinyMCE, which fails to properly enforce the security policy. This specifically affects the encoding directive and the valid elements attribute, allowing for cross-site scripting (XSS) attacks. An example of exploitation involves using a textarea element. **Recommendations** For TinyMCE version 3.5.8, consider disabling the bbcode plugin until a patch is available to prevent potential XSS attacks. Restrict access to the valid elements attribute and encoding directive to minimize the risk of exploitation.
