Live codes a Spring Boot + Spring Security + Thymeleaf app using Copilot and ChatGPT, produces working endpoints that initially contain glaring flaws, and demonstrates exploitation with Burp Suite: a concatenated query allows SQL injection, output enables XSS, and file uploads permit path traversal. A Snyk scan flags issues immediately, fixes include named query parameters to block injection and path normalization to stop traversal, and the talk cites the striking claim that about 40% vulnerable code appears in Copilot outputs. SQL injection and path traversal are proven and patched live.
