Executive Summary

This vulnerability is a field-level permissions bypass in the Frappe Framework that allows unauthorized access to restricted DocType fields through the Document Follow feature. It affects versions before 16.23.0 and 15.112.0.

Detection Guidance

To detect this vulnerability, check the Frappe Framework version installed on your system. Run the command grep -r 'version' /path/to/frappe/installation to verify if it is below 16.23.0 or 15.112.0. If so, the system is vulnerable.

Impact Analysis

Unauthorized users could view sensitive field changes in the document follow changelog that they are not permitted to access. This could lead to exposure of restricted data depending on the DocType fields affected.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, potentially violating compliance requirements such as GDPR (data protection) or HIPAA (health information privacy) if restricted fields contain protected information.

Mitigation Strategies

Update Frappe Framework to version 16.23.0 or later if using version 16.x, or to version 15.112.0 or later if using version 15.x. This resolves the field-level permission bypass vulnerability.
