CVE-2026-29784 (GCVE-0-2026-29784)

Vulnerability from cvelistv5 – Published: 2026-03-07 15:30 – Updated: 2026-03-09 18:26

Title

Ghost: Incomplete CSRF protections around OTC use

Summary

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.

Severity ?

7.5 (High)
