Episode 189 | OWASP Top 10 Part 3: Software Supply Chain Failures — From SolarWinds to Vibe Coding

Almost no one writes an application from scratch anymore, and that's exactly the problem. In Part 3 of our OWASP Top 10 series, Brad Causey and Jordan Natter break down A03: Software Supply Chain Failures, the category that climbed to #3 and topped OWASP's own community survey as the vulnerability organizations worry about most. If your team pulls in third-party libraries, buys SaaS, or lets anyone "vibe code" a project, this episode is for you.Brad and Jordan cover both sides of supply chain risk: the trusted third-party applications you deploy (SolarWinds being the case that put this category on the map) and the open-source components you pull into your own code without always knowing what's inside. They explain why AI and vibe coding are accelerating the problem, why jQuery is the modern-day Flash, and why "just upgrade the package" is rarely that simple.From there it gets practical:What a Software Bill of Materials (SBOM) is and why you need oneTransitive dependencies — the packages hiding beneath your packagesBuilding security checks into your CI/CD pipeline and shifting leftWhy a flaw caught in static analysis can cost ~$200, while the same flaw found in a pen test can cost $20,000+Why a pen test should validate your controls, not be your first line of defenseHow SecurIT360's Project Lantern and ChainGarde automate SBOM analysis against known and actively-exploited vulnerabilitiesA playbook for vetting vendors, writing accountability into contracts, and holding third parties responsible for actually fixing findingsThe takeaway: whether you're writing software or buying it, you need a way to inventory your components, check them against known vulnerabilities, and hold your vendors accountable — and most of it you can do with tools and teams you already have.Part 1 — Broken Access Control, IDOR & CORS: https://youtu.be/BwYJ-kZ3XaYPart 2 — Security Misconfigurations: https://youtu.be/Po8H140BijENeed a web app pen test?
