What is CVE-2022-47194?

A vulnerability exists in the Post Creation functionality of Ghost 5.9.4 that allows non-administrative users to inject arbitrary JavaScript into posts due to insecure default configurations. This may lead to privilege escalation via stored cross-site scripting (XSS). Specifically, an attacker could exploit the twitter field for a user to execute their injected scripts when an administrator is tricked into visiting the malicious post. Proper configurations and validation mechanisms are essential to mitigate this risk.
