CST VerdictBased on our analysis of available product data, here is our conclusion:
OWASP Damn Vulnerable Web Sockets (DVWS)
Security teams building or testing real-time applications should use OWASP Damn Vulnerable Web Sockets to close the WebSocket blindspot in their training programs; most developers never encounter these vulnerabilities in labs because frameworks like OWASP WebGoat don't cover persistent bidirectional connections. The 356 GitHub stars and zero licensing friction mean you can spin up a shared lab environment across your entire engineering org without budget negotiation. Skip this if your team only cares about HTTP-based OWASP Top 10 coverage; DVWS is narrow by design and teaches one thing well rather than serving as a general-purpose vulnerable app.
