XenForo 2.0.11 is now available for download. This release was released to address a potential vulnerability. We recommend that all clients using XenForo 2.0 upgrade to version 2.0.11 as soon as possible. The problem is the vulnerability of XSS. Problems with XSS (Cross Site Scripting) allow scripts and malicious HTML to be inserted into the page, which potentially allows data theft or unauthorized access. In particular, the problem is related to specially created text that is entered into messages and output using a structured text system (used in profile messages and comments).
