DescriptionGitHub Advisory

Ghost is a Node.js content management system. From version 5.101.6 to 6.19.2, incomplete CSRF protections around /session/verify made it possible to use OTCs in login sessions different from the requesting session. In some scenarios this might have made it easier for phishers to take over a Ghost site. This issue has been patched in version 6.19.3.

AnalysisAI

Cross-site request forgery (CSRF) in Ghost CMS versions 5.101.6 through 6.19.2 permits attackers to reuse one-time codes across different login sessions via the /session/verify endpoint, potentially enabling account takeover through phishing attacks. The vulnerability affects Ghost deployments on Node.js and related platforms, requiring no user authentication but relying on user interaction. A patch is available in Ghost version 6.19.3 and later.
