This patch addresses three important issues. All were found after the launch of 5.0.2.

1. One fix corrects the importing of closed threads.
2. Another fix addresses a potential infinite redirection loop that could possibly occur in the conversation route.
3. A method was repaired when it was found to be vulnerable to a potential SQL Injection.

This patch affects only vBulletin 5.0.2. vBulletin 3, vBulletin 4, vBulletin 5.0.0 and vBulletin 5.0.1 are not affected.

New downloads of vBulletin 5.0.2 (and beyond) include all these updates. There is no need to utilize the steps below if you downloaded vB 5.0.2 today after 3:30PM PT or beyond.
