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.
Weakness
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
