Modern software development relies heavily on third-party dependencies, which often introduce security vulnerabilities. This paper presents Dependency Guard, a web-based vulnerability detection system that utilizes the OSV API to identify known security issues in software packages. The system allows users to input package details and retrieve real-time vulnerability data including CVE IDs, severity levels, and CVSS scores. Built using Flask, the system provides a lightweight and efficient solution for developers and students to enhance software security. Experimental results show that the system accurately detects vulnerabilities and provides timely insights.

The Dependency Guard system provides a simple and effective solution for detecting vulnerabilities in software dependencies. By using the OSV API, the system is able to identify known security issues and present accurate results in real time. The user-friendly interface makes it easy for students and developers to analyze the security of their applications. The system helps in increasing awareness about dependency-related risks and promotes secure coding practices. It reduces the effort required for manual vulnerability checking and improves overall software security. In the future, the system can be enhanced by adding features such as automatic project scanning, integration with GitHub, and advanced risk analysis.
