Improper authentication in Progress MarkLogic Server SAML processing

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.

Progress MarkLogic Server 12.x releases before 12.1.0 and 11.x releases before 11.3.7 contain an improper authentication vulnerability in SAML processing. In deployments that use SAML authentication, an unauthenticated remote attacker could cause the affected server to accept an assertion that should be rejected, potentially resulting in unauthorized access.
