Software Supply Chain Failures: A detailed vulnerability study with applicable remediations for PHP-based applications

Abstract

In today's digital age, where organizations move from local to global, they use web applications to automate their processes. Many organizations rely on third-party software to handle payments. However, some still use old software that they can't update, or they use outdated features. These outdated systems can make their applications weak and easy to attack. Software supply chain failure is ranked as 3 in the OWASP Top 10 list in 2025, consisting of 5 sub-vulnerabilities. In this research paper we will be talking about real-time test cases and possible mitigation methodologies. We will discuss possible remediation techniques that can be adopted by the developers when developing the product.
