| Title | a2aproject a2a-dotnet v1.0 CWE-362 |
|---|
| Description | TaskProjection.ApplyStatus unconditionally overwrote current.Status, and ApplyMessage unconditionally appended to history. A task in a terminal state (COMPLETED/CANCELED/FAILED/REJECTED) could be overwritten back to SUBMITTED or accept further messages via direct state assignment, whenever events bypassed the request-level terminal checks (e.g. a misbehaving agent handler emitting events after a terminal status). |
