Overview
Affected versions of this package are vulnerable to Uncontrolled Recursion in the parse_value and parse_json process. An attacker can exhaust server memory and cause a crash by sending a deeply nested JSON payload to the WebSocket /rpc endpoint. This is only exploitable if the attacker has network access to the WebSocket /rpc endpoint.
Workaround
This vulnerability can be mitigated by restricting network access to the WebSocket /rpc endpoint to trusted clients.
