+# JSON Model File DoS and Prototype Pollution PoC
+
+## Vulnerability
+DoS via deeply nested/large JSON + prototype pollution for JS-based ML tools
+
+## Files
+- `poc_deep_nest.json` — 10,000 levels deep, causes stack overflow on json.load()
+- `poc_huge_object.json` — 100K keys, causes excessive memory/CPU on parsing
+- `poc_prototype_pollution.json` — __proto__ pollution payload for TF.js/Node consumers
+
+## Reproduce
+```python
+import json
+# Stack overflow from deep nesting:
+with open('poc_deep_nest.json') as f:
+    json.load(f)  # RecursionError
+```
