| Title | ag-ui-protocol ag-ui v1.0 CWE-400 |
|---|
| Description | The 10 MB size cap is checked against the chunk buffer only; the per-event accumulator (m_currentData) grows without bound, so a single oversized event (delivered in many small chunks) bypasses the cap.
Event payloads are parsed with nlohmann::json without a depth limit; deeply nested JSON triggers unbounded recursion during parsing. |
