If you’re like me, you think of Google Groups as the Usenet client turned mailing list manager. If you’re a GCP user or maybe one of a handful of SAML users you probably know Google Groups as an access control mechanism. The bad news is we’re both right. This can blow up if permissions on those groups aren’t set right. Your groups were probably originally created by a sleep-deprived founder way before anyone was worried about access control.
