CVE-2026-105675 · Severity: high · CVSS 7.5 · Published 2026-10-05

Ghost is a Node.js-based content management system used to publish websites and newsletters. A vulnerability in versions 4.39.0 through 6.63.0 allows staff members with permission to view staff invitations to discover secret tokens for pending invites, including those for higher-privileged roles. An attacker could use these tokens to accept invitations and escalate their privileges within the system.

## How to fix

- Fixed in 6.64.0

## Technical details

The Admin API insufficiently validates filter and order parameters, allowing authenticated staff users to extract sensitive invite tokens from the system. The vulnerability affects the staff invites endpoint accessible to users with appropriate permissions. The attack requires valid staff authentication and knowledge of the invite viewing feature; exploitation enables privilege escalation by accepting high-privilege invitations that were not intended for the attacker.
