XF2 XenForo 2.2.16 - Nulled

[dEEpEst]

Security Fix

Today we are advising all customers running XenForo that a potential security vulnerability has been identified. All affected customers should either upgrade to XenForo 2.1.15 or XenForo 2.2.16.

If you are a XenForo Cloud customer, a fix has been rolled out automatically, and no further action is required to address this issue.

If you are running a pre-release version of XenForo 2.3, you should follow the instructions in the announcement thread for the XenForo 2.3.0 Release Candidate 1 release.

The issue relates to a potential cross-site request forgery and code injection vulnerability which could lead to a remote code execution (RCE) or cross-site scripting (XSS) exploit.

XenForo extends thanks to independent security researcher, Egidio Romano (EgiX), working with SSD Secure Disclosure.

We recommend doing a full upgrade to resolve the issue, but a patch can be applied manually to any version. See below for further details.
