Detailsinfo

A vulnerability classified as critical has been found in OpenClaw, Clawdbot and Moltbot up to 2026.2.0. This affects an unknown code of the component Webhook Endpoint. The manipulation with an unknown input leads to a data authenticity vulnerability. CWE is classifying the issue as CWE-345. The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

OpenClaw is a personal AI assistant. In versions 2026.1.30 and below, if channels.telegram.webhookSecret is not set when in Telegram webhook mode, OpenClaw may accept webhook HTTP requests without verifying Telegram’s secret token header. In deployments where the webhook endpoint is reachable by an attacker, this can allow forged Telegram updates (for example spoofing message.from.id). If an attacker can reach the webhook endpoint, they may be able to send forged updates that are processed as if they came from Telegram. Depending on enabled commands/tools and configuration, this could lead to unintended bot actions. Note: Telegram webhook mode is not enabled by default. It is enabled only when `channels.telegram.webhookUrl` is configured. This issue has been fixed in version 2026.2.1.
