✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: To mitigate this vulnerability, it is recommended to disable the urwid web display backend if its functionality is not essential for your environment. If the urwid web display backend must remain active, restrict network access to the service to trusted clients only by implementing appropriate firewall rules. This will limit the exposure to remote attackers attempting to reconstruct session IDs. Additionally, ensure that local system configurations prevent unauthorized access to temporary files, which could otherwise allow local users to enumerate active session tokens. Any changes to service configurations may require a service restart to take effect.
