OpenClaw < 2026.3.13 - Resource Exhaustion via Unauthenticated Telegram Webhook Request

Platform

other

Component

openclaw

Fixed in

2026.3.13

OpenClaw before 2026.3.13 reads and buffers Telegram webhook request bodies before validating the x-telegram-bot-api-secret-token header, allowing unauthenticated attackers to exhaust server resources. Attackers can send POST requests to the webhook endpoint to force memory consumption, socket time, and JSON parsing work before authentication validation occurs.

How to fix

Actualice OpenClaw a la versión 2026.3.13 o superior. Esta versión corrige la vulnerabilidad de agotamiento de recursos al validar el encabezado x-telegram-bot-api-secret-token antes de procesar el cuerpo de la solicitud.
