CVE-2026-28454
HIGHOpenClaw < 2026.2.2 - Unauthenticated Privileged Command Execution via Telegram Webhook Spoofing
Title source: llmDescription
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.
