CVE-2026-110768 holaboss-ai CVE debrief
CVE-2026-110768 is an authorization bypass vulnerability in holaOS through version 2026.822.1. The vulnerability is located in the Telegram connector of the channel-gateway, where senders are authorized by mutable username instead of numeric id. This allows attackers who register a released username listed in allowFrom to submit turns to the bound workspace agent, which runs configured tools on the operator's machine.
