What is CVE-2026-110769?

holaOS, through version 2026.822.1, contains a missing authorization flaw in its channel-gateway connectors. This vulnerability allows any user of the messaging platform to submit agent tasks because the system's #isAllowed check indiscriminately accepts all senders when the default allowFrom list remains empty. Attackers who gain access to the operator's messaging accounts on Telegram, Slack, Discord, or other platforms can exploit this flaw, leading to potential unauthorized execution of configured tools on the operator's machine via the ChannelIngress.handle function.

Exploit Proof of Concept (PoC)
