| Título | a2ui-project a2ui v1.0 CWE-200 |
|---|
| Descrição | The v0_8 model processor resolves JSON Pointer reads by walking plain objects (current[segment], model-processor.ts:356-377). Properties inherited through the prototype chain (e.g. Object.prototype built-ins) are therefore reachable by agent-supplied paths.
Notes on scope:
The v0_8 write path is Map-based and unaffected.
The v0_9 path rejects dangerous keys (__proto__/constructor/prototype) after unescaping. |
