AnalysisAIv1 – Mar 12, 2026

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.

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.

Executive ViewAI

Why It Matters

Ghost CMS instances running versions 5.101.6 through 6.19.2 are vulnerable to cross-site request forgery (CSRF) attacks that could allow attackers to hijack user login sessions without credentials. Organizations using affected Ghost versions face potential unauthorized administrative access and content manipulation risks.

Business Impact: High
Compensating Controls

Apply vendor patch. If immediate patching is not possible: implement WAF rules to block requests to /session/verify endpoints from untrusted origins, enforce strict same-site cookie policies, enable CSRF token validation logging, and restrict administrative access through network segmentation or IP whitelisting.
