WHMCS Security Advisory for 5.x
UPDATE 2: We have published 5.2.12 incremental and full versions. These include all security related enhancements as well as the missing file that triggers the version increment.
Please Note: if you downloaded 5.2.11, your update is incomplete. Please deploy 5.2.12 to ensure the software version increments properly. Version 5.1.13 was not affected by this packaging deficiency.
UPDATE: We've identified a missing file in 5.2.11 which causes the version number not to increment. All security related enhancements are present. We will be updating this post again with version 5.2.12 which will contain the complete change set. Thank you for you patience.
