Description Robb Gatica 2023-10-12 00:54:47 UTC

Separate Groups mode restrictions were not honored in the forum summary report, which would display users from other groups. This flaw affects versions 4.2 to 4.2.2, 4.1 to 4.1.5, 4.0 to 4.0.10, 3.11 to 3.11.16, 3.9 to 3.9.23 and earlier unsupported versions.
