XenForo 2.3.9 Released Full | XenForo Nulled 2.3.9

The issues identified are as follows:

• Prevention of a possible stored XSS (cross-site scripting) exploit related to BB code rendering (thank you to Antisocial)

• Prevention of a possible XSS exploit related to lightbox usage in posts (thank you UwU)

• Prevention of a possible RCE (remote code execution) exploit via authenticated, but malicious, admin users (thank you UwU)

If you are a XenForo Cloud customer, fixes for these issues have been rolled out automatically, and no further action is required to address them.

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

If you are a XenForo Cloud customer, your installations have already been patched and no further action is required. You will remain on version 2.3.8 until 2.3.10 is released.
