Summary

Ghost from 6.54.1 before 6.65.0 is affected. A validation issue lets an unauthenticated remote attacker make limited HTTP requests to hosts on the Ghost server's internal network through features such as Webmentions, which is server-side request forgery (CWE-918). The attacker receives no response data from those requests.

Description from the CNA

Ghost is a Node.js content management system. From 6.54.1 until 6.65.0, a validation issue allowed some functionality, such as Webmentions, to be abused by an unauthenticated user to make limited HTTP requests to hosts in the Ghost server's internal network. A successful attack would not result in any response data being returned. This issue is fixed in version 6.65.0.
