Name of the Vulnerable Software and Affected Versions
Ghost versions 6.0.9 through 6.21.0
Description
Ghost is a Node.js content management system. A flaw in the private-IP check for outbound HTTP requests allows a bypass via DNS rebinding. DNS rebinding is a technique that tricks a browser or server into accessing a private network address by changing the DNS record of a domain after the initial check. This allows an attacker to force the server to reach hosts on internal networks through features that perform external fetches.
Recommendations
Update to version 6.21.1.
