CVE-2026-28454: OpenClaw has a potential access-group authorization bypass if channel type lookup fails
(updated )
When Telegram webhook mode is enabled without a configured webhook secret, OpenClaw may accept unauthenticated HTTP POST requests at the Telegram webhook endpoint and trust attacker-controlled update JSON. This can allow forged Telegram updates that spoof message.from.id / chat.id, potentially bypassing sender allowlists and executing privileged bot commands.
