A fix is available — apply it.

Ghost versions from 2.21.0 before 6.56.0 contain a privilege escalation vulnerability in the notifications system that allows low-privilege staff users to escalate to higher-privilege staff roles. Attackers with low-privilege staff access can exploit the notifications system to gain elevated privileges without proper authorization checks.
