What
A request to open network access from inside the sandbox is now dropped unless the worker name in the request matches the teammate who sent the message. Requests missing a host or worker name, or carrying non-text values for them, are also dropped. This closes a path where one worker could ask for network access in another's name.
Evidence
workerName ${S(wo.workerName)} does not match sender
