What is CVE-2022-47195?

A security vulnerability exists in the Post Creation functionality of Ghost Foundation's Ghost version 5.9.4. This flaw allows non-administrator users to inject arbitrary JavaScript into posts due to insecure default settings. An attacker can exploit this by sending a crafted HTTP request to include malicious JavaScript in a post, potentially tricking an administrator into visiting the compromised post. A stored XSS vulnerability is also present in the facebook field for user profiles, further increasing the risk of privilege escalation to administrator level.
