📄 الوصف (الإنجليزية)
OpenClaw versions prior to 2026.2.26 fail to enforce sender authorization in member and message subtype system event handlers, allowing unauthorized events to be enqueued. Attackers can bypass Slack DM allowlists and per-channel user allowlists by sending system events from non-allowlisted senders through message_changed, message_deleted, and thread_broadcast events.
🤖 ملخص AI
OpenClaw versions before 2026.2.26 contain an authorization bypass vulnerability (CVE-2026-32895) that allows attackers to circumvent Slack DM and channel-level user allowlists by spoofing system events. While currently unpatched with no public exploits, this medium-severity vulnerability (CVSS 5.4) could enable unauthorized message injection and information disclosure in organizations using OpenClaw for Slack integration and access control. Saudi organizations relying on OpenClaw for secure Slack communications should assess their exposure and implement compensating controls immediately.

🇸🇦 التأثير على المملكة العربية السعودية
Saudi organizations in financial services (banking sector under SAMA oversight), government agencies (NCA, CITC), and large enterprises using OpenClaw for Slack-based access control face risks of unauthorized message injection and potential information disclosure. The vulnerability is particularly concerning for organizations with strict data classification requirements and those handling sensitive communications. Government entities and ARAMCO-affiliated organizations using Slack with OpenClaw integration for secure communications could experience unauthorized access to restricted channels and DMs, potentially violating NCA ECC 2024 access control requirements.

🔧 Remediation Steps (English)
Immediate Actions:
1. Audit all OpenClaw deployments to identify versions prior to 2026.2.26
2. Review Slack workspace access logs for suspicious system events (message_changed, message_deleted, thread_broadcast) from unexpected senders
3. Disable OpenClaw integration temporarily if critical data is at risk
Compensating Controls (until patch available):
1. Implement additional Slack workspace-level access controls and restrict bot permissions
2. Enable Slack audit logging and monitor for anomalous event patterns
3. Restrict OpenClaw bot token permissions to minimum required scope
4. Implement network-level monitoring for OpenClaw API calls
5. Review and strengthen Slack allowlist configurations manually
Patching Guidance:
1. Upgrade to OpenClaw 2026.2.26 or later immediately upon release
2. Test in non-production environment first
3. Verify allowlist enforcement after upgrade
Detection Rules:
1. Monitor for message_changed, message_deleted, thread_broadcast events from non-allowlisted senders
2. Alert on system events originating from unexpected service accounts
3. Track failed authorization attempts in OpenClaw logs
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع نشرات OpenClaw لتحديد الإصدارات السابقة للإصدار 2026.2.26
2. مراجعة سجلات وصول مساحة عمل Slack للأحداث المريبة (message_changed, message_deleted, thread_broadcast) من مرسلين غير متوقعين
3. تعطيل تكامل OpenClaw مؤقتاً إذا كانت البيانات الحرجة معرضة للخطر
الضوابط التعويضية (حتى توفر التصحيح):
1. تطبيق ضوابط وصول إضافية على مستوى مساحة عمل Slack وتقييد أذونات البوت
2. تفعيل تسجيل تدقيق Slack ومراقبة أنماط الأحداث الشاذة
3. تقييد أذونات رمز بوت OpenClaw للنطاق المطلوب بحد أدنى
4. تطبيق مراقبة على مستوى الشبكة لاستدعاءات OpenClaw API
5. مراجعة وتعزيز تكوينات قائمة السماح في Slack يدوياً
إرشادات التصحيح:
1. الترقية إلى OpenClaw 2026.2.26 أو إصدار أحدث فوراً عند توفره
2. الاختبار في بيئة غير الإنتاج أولاً
3. التحقق من إنفاذ قائمة السماح بعد الترقية
قواعد الكشف:
1. مراقبة أحداث message_changed و message_deleted و thread_broadcast من مرسلين غير مدرجين في قائمة السماح
2. تنبيه على أحداث النظام الناشئة من حسابات خدمة غير متوقعة
3. تتبع محاولات التفويض الفاشلة في سجلات OpenClaw
