How to fix?

Upgrade Chainguard grafana-fips-12.4 to version 12.4.11-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream grafana-fips-12.4 package and not the grafana-fips-12.4 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

When SAML IdP-initiated login is enabled in Grafana Enterprise, the SAML library skips validation of the InResponseTo field on all SAML responses, including SP-initiated logins. This removes anti-replay protection, allowing an attacker who obtains a valid signed SAML assertion to replay it and gain a session as the victim user. Only instances with the allow_idp_initiated SAML setting enabled are affected; this setting is off by default and Grafana OSS is not affected.
