Summary

CVE-2026-29784 is a high-severity CSRF (CWE-352) vulnerability in Ghost Ghost. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SC-23 (Session Authenticity) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-29784 is a cross-site request forgery (CSRF) vulnerability, classified under CWE-352, affecting Ghost, a Node.js content management system. The issue stems from incomplete CSRF protections around the /session/verify endpoint in versions 5.101.6 through 6.19.2. This flaw allows one-time codes (OTCs) intended for one login session to be used in a different session, with a CVSS v3.1 base score of 7.5 (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H).

Remote unauthenticated attackers can exploit this vulnerability by tricking authenticated users into interacting with a malicious site or resource, such as through phishing. The high attack complexity and required user interaction enable phishers in certain scenarios to hijack login sessions and take over a Ghost site, potentially leading to high-impact confidentiality, integrity, and availability compromises.

The Ghost security advisory (GHSA-9m84-wc28-w895) and associated patch commit detail mitigation through updates to version 6.19.3, which addresses the incomplete CSRF protections in the /session/verify endpoint. Security practitioners should upgrade affected Ghost instances immediately and review configurations for proper CSRF token handling.

Vulnerability Data

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…

Mitigating Controls (NIST 800-53 r5) AI

Access enforcement requires verifying that state-changing requests originate from the authenticated user rather than a forged cross-site source.

Protecting session authenticity prevents attackers from replaying or forging authenticated requests via the victim's browser.
