A vulnerability has been reported in vBulletin 3.0.0 beta 2. The problem is said to occur due to insufficient sanitization of private messages. As a result, an attacker may be capable of embedding malicious HTML or script code within a private message. This code may be interpreted by a legitimate user when previewing the message.

|
It should be noted that vBulletin 3.0.0 beta 2 is not a public release and has only been made available to a small portion of selected sites. This issue does not affect any public releases of vBulletin.
