This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4% (31st percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Ghost is a Node.js content management system. From 4.39.0 until 6.64.0, staff users with permission to view staff invites were able to discover the secret token of pending invites, including invites for roles with higher privileges than their own. This could allow a staff user to escalate their privileges by accepting a pending invite. This issue is fixed in version 6.64.0.
