CVE-2026-32980 PUBLISHED

OpenClaw < 2026.3.13 - Resource Exhaustion via Unauthenticated Telegram Webhook Request

Assigner: VulnCheck
Reserved: 17.03.2026 Published: 29.03.2026 Updated: 29.03.2026

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.
