Grab your seat nowPractical web application security guided by real-world CVEs
One-day workshop by Philippe De Ryck in room West Wing
This workshop explores modern web application security through the lens of recent real-world CVEs. Instead of focusing on theory, we analyze how vulnerabilities such as path traversal, JWT handling flaws, authorization bypasses, and command injection appear in practice. By dissecting real incidents, we uncover common patterns, root causes, and exploitation techniques. The workshop connects these findings to concrete defensive strategies, helping you understand not just what goes wrong, but how to prevent it in modern applications.
Learning goal: Learn core web application security concepts and how they manifest in real-world vulnerabilities, using recent CVEs as context to understand and prevent common issues.
