= Conclusion

This security audit provides a comprehensive assessment of the OSVM CLI application's security posture. All identified findings should be addressed according to their severity level, with critical and high-severity issues taking priority. Regular security assessments and continuous monitoring are recommended to maintain a strong security stance.
