Recurring patterns

Code Injection: Untrusted regex strings in proto definitions can break out of double-quoted Go string literals during code generation, allowing malicious protobuf files to inject and execute arbitrary Go code during compilation. This is a severe threat to developers and build pipelines processing untrusted proto files.

Input Validation: Naming resolution bugs for complex protobuf structures like oneof fields can cause the generator to silently drop regex validation constraints or reference non-existent variables, resulting in silent validation bypasses in downstream applications.

Input Validation: The validator plugin historically failed to enforce enum boundary checks, accepting undefined enum integers and bypassing logical constraints unless explicit enum validation is generated and executed.
