| Title | a2aproject a2a-go ≤ v2.4.0 CWE-400 |
|---|
| Description | The REST SSE handler creates panicChan unbuffered, so a panic after the client disconnects is never read and the goroutine blocks forever on the send. A remote client can trigger this repeatedly by disconnecting while streaming, permanently consuming a goroutine and its stack each time, causing unbounded memory growth. |
