Ghost is a Node.js content management system. In versions 5.121.0 through 5.130.5 and 6.0.0 through 6.10.3, a vulnerability in Ghost's handling of Staff Token authentication allowed certain endpoints to be accessed that were only intended to be accessible via Staff Session authentication. External systems that have been authenticated via Staff Tokens for Admin/Owner-role users would have had access to these endpoints. This issue has been patched in versions 5.130.6 and 6.11.0.
AnalysisAI
Ghost CMS versions 5.121.0-5.130.5 and 6.0.0-6.10.3 incorrectly allow Staff Token authentication to access endpoints restricted to Staff Session authentication, enabling authenticated Admin/Owner-role users to perform unauthorized actions. An attacker with valid Staff Token credentials for elevated roles could bypass authentication restrictions and access sensitive endpoints not intended for token-based access. Patches are available in versions 5.130.6 and 6.11.0.
