A new critical vulnerability has been found in the GitHub Enterprise Server! CVE-2024-9487, with a staggering CVSS score of 9.5, is a cryptographic signature verification flaw that allows an attacker to gain unauthorized access to vulnerable instances.78io.-[

The encrypted assertions feature, which is not enabled by default, can bypass SAML SSO with a crafted SAML response. This issue emerged as a result of follow-up remediation efforts for CVE-2024-4985. Exploiting this vulnerability requires an attacker to have direct network access and a signed SAML response or metadata document. This flaw does not affect instances not using SAML SSO or encrypted assertions.
