Unauthenticated group assignment via unchecked registration role
Published Sep 6, 2026 · Updated Sep 6, 2026
Missing authorization in WebWizards B2BKing before 5.2.40 allows remote attackers to join restricted groups during registration. The self-registration handler accepts the submitted role identifier without checking that the selected role appears among the registration form's offered choices. An unauthenticated registrant can therefore bypass manual account approval and obtain the pricing and purchasing rules assigned to a restricted B2B group.
