CVE-2026-110768

Description

holaOS through 2026.822.1 contains an authorization bypass vulnerability in the channel-gateway Telegram connector that authorizes senders by mutable username rather than only numeric id. Attackers who register a released username listed in allowFrom can submit turns to the bound workspace agent, which runs configured tools on the operator's machine.
