When accessing the section 2.3.6. Read-only user attributes from the Upgrading Guide, there is a mention to the Threat model mitigation chapter:

For more details, see the Threat model mitigation chapter.

However, the Threat model mitigation chapter link is broken in both the RH SSO 7.5 and 7.6 Documentation: It redirects to the Upgrading Guide, but not for the relevant chapter.

The correct links should be:

• RH SSO 7.5: https://access.redhat.com/documentation/en-us/red_hat_single_sign-on/7.5/html-single/server_administration_guide/index#mitigating_security_threats
• RH SSO 7.6: https://access.redhat.com/documentation/en-us/red_hat_single_sign-on/7.6/html-single/server_administration_guide/index#mitigating_security_threats
