What is CVE-2022-47196?

A security flaw exists in the Post Creation functionality of Ghost Foundation's software, specifically in version 5.9.4. Default configurations permit unauthorized users to inject arbitrary JavaScript into posts. This can lead to privilege escalation through cross-site scripting (XSS) if an attacker successfully tricks an administrator into visiting a compromised post. The vulnerability also involves stored XSS within the codeinjection_head segment of a post, further exposing the system to potential exploits. It's essential for users to review their configurations and apply necessary updates to mitigate this risk.
