Title
Obot 0.25.0 before 0.25.6 and 0.26.0 before 0.26.1 Race Condition Restores Revoked Group Membership
Summary
Obot 0.25.0 before 0.25.6 and 0.26.0 before 0.26.1 contains a race condition in auth provider group refreshes that can restore group memberships just revoked in the identity provider. When overlapping refreshes for the same user commit out of order, stale memberships are persisted and the user retains revoked group-based access for about ten minutes.
