Summary

holaOS through 2026.822.1 has a missing authorization flaw in its channel gateway connectors. The #isAllowed check accepts all senders when the default allowFrom list is empty, which is an insecure default (CWE-1188). Any messaging-platform user who can message the operator's Telegram, Slack, Discord or other bot can have the workspace agent run configured tools on the operator's machine. An exploit link appears in the references.
