| Titel | a2aproject a2a-go ≤ v2.4.0 CWE-404 |
|---|
| Beschreibung | In internal/taskexec/distributed_manager.go, after distributedManager.Cancel creates a reader via CreateReader, every early return - context encoding failure, task-store reload error, and the already-canceled or terminal branches - returns without closing it, leaking the reader and its registration on each cancel. Repeated cancellations of tasks that hit these branches accumulate leaked readers and registrations without bound, so an unauthenticated or low-privileged caller can steadily consume server resources by issuing cancels, degrading or eventually exhausting the service. |
