Executive Summary

Ghost versions 5.3.0 before 6.58.0 fail to enforce access controls on comments in private mode. Unauthenticated visitors can read comments that should be restricted, bypassing privacy settings. The flaw is due to missing authorization checks, allowing unauthorized access to private comments.

Detection Guidance

To detect this vulnerability, check your Ghost version. If it is between 5.3.0 and 6.58.0, it is vulnerable. Run 'ghost version' in your Ghost CLI or check the version in your Docker container logs.

Impact Analysis

This vulnerability allows unauthorized users to read private comments on Ghost sites running vulnerable versions. It compromises confidentiality by exposing sensitive information meant to be restricted. Users should update to version 6.58.0 or later to mitigate the risk.

Compliance Impact

This vulnerability could lead to non-compliance with privacy regulations like GDPR or HIPAA by exposing private user data. Unauthorized access to restricted comments may violate data protection requirements, potentially resulting in legal or regulatory penalties.
