Obot 0.25.0 before 0.25.6 and 0.26.0 before 0.26.1 Race Condition Restores Revoked Group Membership

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
