All affected installations are encouraged to upgrade as soon as possible. Vulnerability Details ===================== Class: Information Leak Versions: 3.3.2 to 3.4.3, 3.5 to 3.5.1 Fixed In: 3.4.4, 3.5.2 Description: When a bug is in a group, none of its information (other than its status and resolution) should be visible to users outside that group.
