Keycloak's missing timestamp validation allows attackers to extend SAML response validity periods
A flaw was found in Keycloak's SAML brokering functionality. When Keycloak is configured as a client in a Security Assertion Markup Language (SAML) setup, it fails to validate the `NotOnOrAfter` timestamp within the `SubjectConfirmationData`. This allows an attacker to delay the expiration of SAML responses, potentially extending the time a response is considered valid and leading to unexpected session durations or resource consumption.

A flaw was found in the keycloak-services component of Keycloak. This vulnerability allows the issuance of access and refresh tokens for disabled users, leading to unauthorized use of previously revoked privileges, via a business logic vulnerability in the Token Exchange implementation when a privileged client invokes the token exchange flow.
