5. Deploy Content Security Policy (CSP) headers: Content-Security-Policy: script-src 'self'; object-src 'none'
6. Implement HTML entity encoding for all long_description output using htmlspecialchars() or equivalent
7. Use DOMPurify or similar library to sanitize user input before storage
8. Enable HTTP-only and Secure flags on session cookies
DETECTION:
9. Monitor for POST/PUT requests to episode endpoints containing <script>, javascript:, onerror=, onload=, onclick= patterns
10. Alert on long_description fields exceeding typical content length (>5000 characters)
11. Review user activity logs for episodes viewed by multiple users after suspicious edits
PATCHING:
12. Contact Podcast Generator developers for security patch status; consider migration to actively maintained alternatives if no patch timeline provided

7. استخدام مكتبة DOMPurify أو مماثلة لتنظيف مدخلات المستخدم قبل التخزين
8. تفعيل أعلام HTTP-only و Secure على ملفات تعريف الجلسة
الكشف:
9. مراقبة طلبات POST/PUT إلى نقاط نهاية الحلقات التي تحتوي على أنماط <script>، javascript:، onerror=، onload=، onclick=
10. التنبيه على حقول long_description التي تتجاوز طول المحتوى النموذجي (>5000 حرف)
11. مراجعة سجلات نشاط المستخدم للحلقات التي يعرضها عدة مستخدمين بعد التعديلات المريبة
