**CRITICAL**: On instances that use SAML single sign-on (SSO) authentication with the optional encrypted assertions feature, an attacker could forge a SAML response to provision and/or gain access to a user with administrator privileges.
|
|
|
|
Please note that encrypted assertions are not enabled by default. Instances not utilizing SAML SSO or utilizing SAML SSO authentication without encrypted assertions are not impacted. Exploitation of this vulnerability would allow unauthorized access to the instance without requiring prior authentication. GitHub has requested CVE ID [CVE-2024-4985](https://nvd.nist.gov/vuln/detail/CVE-2024-4985) for this vulnerability, which was reported via the [GitHub Bug Bounty program](https://bounty.github.com/).

During the validation phase of a configuration run, a `No such object` error may occur for the Notebook and Viewscreen services. This error can be ignored as the services should still correctly start.

If the root site administrator is locked out of the Management Console after failed login attempts, the account does not unlock automatically after the defined lockout time. Someone with administrative SSH access to the instance must unlock the account using the administrative shell. For more information, see "[AUTOTITLE](/admin/configuration/administering-your-instance-from-the-management-console/troubleshooting-access-to-the-management-console#unlocking-the-root-site-administrator-account)."

If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using `ghe-ssl-ca-certificate-install` are not respected, and connections to the server fail.

The `mbind: Operation not permitted` error in the `/var/log/mysql/mysql.err` file can be ignored. MySQL 8 does not gracefully handle when the `CAP_SYS_NICE` capability isn't required, and outputs an error instead of a warning.
