Authentication Source Verification Issue in Okta Access Gateway

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.

Okta Access Gateway (OAG) does not validate the selected authentication source during sign-on. An authenticated user with an active session can modify the authentication source parameter, which may generate a SAML assertion granting access to the Admin Console.
