Executive Summary

This vulnerability allows users with read access to a repository to access environment properties of another repository. Specifically, a caller can select a readable repository parameter while retrieving environment properties for a protected build, which may expose build environment secrets.

Impact Analysis

The impact includes confidentiality breaches where sensitive build environment secrets could be exposed. This could lead to unauthorized access to confidential data, but there is no demonstrated impact on integrity or availability of systems.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive build environment secrets, which may include personal or health data. This could violate GDPR's data protection principles or HIPAA's confidentiality requirements if such data is exposed.

Mitigation Strategies

Restrict repository parameter access to authorized users only. Review and update repository permissions to ensure least privilege. Monitor build environment secrets for unauthorized access attempts.
