CVE-2026-32980: Openclaw

High severity, CVSS 7.5. EPSS: 0.7% chance of exploitation in the next 30 days.

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.
