Why Ruby & PHP are breaking right now (and why your WAF can't save you)
Look at the root cause of the latest major security rollouts:
1. PHP: Unauthenticated input bypasses sanitization to drop a shell directly onto the host.
2. Ruby (Onigmo engine): Regular expression vulnerabilities that directly trigger RCEs (the same flaws that brought down enterprise repositories recently).
In both cases, the vulnerability exists because the software layer treats untrusted user input as executable data.
Traditional security tries to intercept this input at Layer 7 (WAFs, API gateways). But once an attacker finds a way to obfuscate the payload, the underlying engine processes it blindly.
The Alternative: Operating at Layer Zero. By treating your framework as a plug-and-play deterministic gate, you strip away the engine's ability to interpret anomalies. Input can't morph into execution because the boundary parameters are mathematically absolute
