Official description

holaOS through 2026.822.1 contains a missing authorization vulnerability in channel-gateway connectors that allows any messaging-platform user to submit agent tasks because the #isAllowed check accepts all senders when the default allowFrom list is empty. Attackers who can message the operator's Telegram, Slack, Discord, or other bot can have ChannelIngress.handle pass turns to the workspace agent, running configured tools on the operator's machine.
