| Doc Text: |
A flaw was found in Wasmtime. This issue allows a Denial of Service (DoS) condition where the host application crashes when canceling pending asynchronous tasks. When an embedder drops or cancels an asynchronous function call before execution begins, cleanup routines fail to handle the missing work item properly and trigger an unhandled error panic. Consequently, an attacker capable of inducing cancellations or timeouts of pending requests can terminate the host process.
