This pull request introduces support for identifying
google.golang.org/protobuf/proto.Messagetypes as potential sources in taint analysis, particularly for gRPC-based services. It includes updates to the taint analysis logic, new helper functions, and additional test cases across multiple vulnerability categories like log injection and SQL injection.Enhancements to taint analysis:
