📄 Description (English)

OpenClaw before 2026.3.22 contains an unauthenticated resource exhaustion vulnerability in voice call webhook handling that buffers request bodies before provider signature checks. Attackers can send large or malicious webhook requests to exhaust server resources without authentication by bypassing signature validation.

🤖 AI Executive Summary

OpenClaw before version 2026.3.22 has an unauthenticated resource exhaustion vulnerability in voice call webhook handling that processes requests before validating provider signatures. Attackers can exploit this by sending large webhook requests to exhaust server resources without authentication.

📄 Description (Arabic)

يؤثر هذا الضعف على معالجات webhook الصوتية في OpenClaw التي تقوم بتخزين مؤقت لأجسام الطلب قبل التحقق من صحة توقيع المزود. يمكن للمهاجمين إرسال طلبات webhook كبيرة أو ضارة لاستنزاف موارد الخادم مثل الذاكرة والمعالج دون الحاجة إلى المصادقة.
