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.

WHMCS has released new patches for the 5.2 and 5.1 minor releases. These updates provide targeted changes to address security concerns with the WHMCS product. You are highly encouraged to update immediately.

WHMCS has rated these updates as having critical & important security impacts. Information on security ratings is available atSecurity Levels - WHMCS Documentation
