CVE-2026-32980 Details
Description
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.
A resource exhaustion vulnerability has been identified in OpenClaw versions prior to 2026.3.13. The issue arises because the application reads and buffers Telegram webhook request bodies before validating the 'x-telegram-bot-api-secret-token' header. This flaw allows unauthenticated attackers to exhaust server resources by sending POST requests to the webhook endpoint. The server consumes memory, socket time, and processes JSON data before authentication is validated, creating a denial-of-service condition.
Users can upgrade to OpenClaw version 2026.3.13 or later, which addresses the vulnerability by validating the Telegram webhook secret before reading and parsing the request body.
