detecting-eval-exec-usage

Scan a source tree for dynamic-code-execution APIs that an attacker can hijack: Python eval / exec / compile, JavaScript eval / Function() / setTimeout(string), Ruby eval / instance_eval / class_eval, Java ScriptEngine, PHP eval / assert($str), .NET Activator.CreateInstance / Reflection.Emit with dynamic input. Use when: pre-commit gate on any application that parses user-uploaded code (rule engines, formula evaluators, plugin systems), or post-bug-report when "we run user-supplied expressions." Threshold: any call to eval / exec / Function / similar where the argument is not a string literal. Trigger with: "scan eval", "find dynamic exec", "audit eval calls", "code injection patterns".
