Fireware OS Improper Authentication in AuthPoint MFA Verification Allows Session Hijacking

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.

An improper authentication vulnerability in WatchGuard Fireware OS's AuthPoint multi-factor authentication process allows a local, unauthenticated attacker on the appliance to hijack another user's in-progress MFA session by supplying a specially crafted request and convincing the victim user to accept an MFA push notification.
