CVE-2026-28454 · OpenClaw < 2026.2.2 - Authorization Bypass via Unauthenticated Telegram Webhook
This page contains facts from public vulnerability sources. Check the original advisory before updating.
OpenClaw versions prior to 2026.2.2 fail to validate webhook secrets in Telegram webhook mode (must be enabled), allowing unauthenticated HTTP POST requests to the webhook endpoint that trust attacker-controlled JSON payloads. Remote attackers can forge Telegram updates by spoofing message.from.id and chat.id fields to bypass sender allowlists and execute privileged bot commands.
