Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Validation bypasses occur when Go code-generation templates fail to emit the underlying lookup map structures for 'in' and 'not_in' rules, silently rendering these verification rules inactive at runtime. This has affected both int32 and int64 validation rules.
Code Injection: Unescaped string values in incoming .proto schema files can be directly interpolated into generated template code and executed dynamically using Python's exec() function, leading to arbitrary code execution during the compilation phase.
Improper Input Validation: A validation bypass existed in UTF8FirstLetterNumBytes where malformed multi-byte UTF-8 sequences allowed invalid strings to evade length boundary constraints due to character undercounting in OneCharLen.
