Security Patch Released for 5.1.8 - 5.2.0 and 5.2.1 Beta

[vB.Org System]

[SIZE=16px]A potential security issue has been discovered by the vBulletin team. This issue could allow private vBulletin options to be accessible to an attacker. To fix this issue, we have created a new security patch. During the process of fixing the issue, it was determined that several options were improperly marked as private. These have been made public for use in templates and elsewhere. It is recommended that all customers install this patch as soon as possible.[/SIZE]
