+# Protocol Buffers FileDescriptorProto option_dependency string materialization DoS PoC
+
+This repository contains a benign security research PoC for a `.pb` artifact
+that drives repeated-string materialization during
+`descriptor_pb2.FileDescriptorProto.ParseFromString(...)`.
+
+Files:
+
+- `control_one_dependency.pb`
+- `malicious_option_dependency_5000000.pb`
+- `reproduce.py`
+
+Observed behavior:
+
+- control artifact:
+  - parses successfully with one `dependency`
+- malicious artifact:
+  - parses successfully with `5,000,000` empty `option_dependency` strings
+  - materially increases peak RSS during normal parse
+
+Tested runtime:
+
+```bash
+python3 -m pip install protobuf==7.35.1
+```
