| Title | a2aproject a2a-rs a2a-server-lf ≤ 0.4.3 CWE-200 |
|---|
| Description | In a2a-server/src/task_store/inmemory.rs a negative historyLength is cast with "as usize", wrapping to usize::MAX and disabling truncation so the full conversation history is returned. In a2a-server/src/rest.rs an unparseable ?status= value is dropped by serde_json::from_value(...).ok(), so no filter is applied and every task is returned. |
