Description

Ghost is a Node.js content management system. From 6.26.0 until 6.54.1, 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 vulnerability is fixed in 6.54.1.
