📄 Description (English)

The LearnPress – Backup & Migration Tool plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.1.4 via deserialization of untrusted input . This makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

🤖 AI Executive Summary

CVE-2026-7566 is a PHP Object Injection vulnerability in LearnPress Backup & Migration Tool plugin (versions ≤4.1.4) affecting WordPress installations. The vulnerability requires authenticated administrator access and depends on the presence of a POP chain in other plugins/themes to achieve impact. While currently no known POP chains exist in the vulnerable software itself, the risk escalates significantly in environments with multiple plugins, which is common in Saudi educational and corporate WordPress deployments.

🇸🇦 Saudi Arabia Impact Assessment
Saudi educational institutions using LearnPress for e-learning platforms face elevated risk, particularly universities and online training providers. Government agencies and corporate entities running WordPress-based learning management systems are vulnerable if multiple plugins are installed. The impact is amplified in organizations with weak plugin governance and those using outdated or unmaintained plugins that may contain POP chains. Healthcare organizations using WordPress for patient education portals and financial institutions with training platforms are secondary targets.

🔧 Remediation Steps (English)
Immediate Actions:
1. Audit all WordPress installations using LearnPress Backup & Migration Tool plugin
2. Restrict administrator account access to trusted personnel only
3. Review and document all installed plugins and themes for known POP chains
4. Implement Web Application Firewall (WAF) rules to detect serialized object patterns

Patching Guidance:
1. Disable the LearnPress Backup & Migration Tool plugin immediately if not actively used
2. Monitor vendor repository for security patches (currently no patch available)
3. Consider alternative backup solutions with better security practices
4. If plugin is critical, implement strict access controls limiting administrator access

Compensating Controls:
1. Enable WordPress security plugins with object injection detection
2. Implement file integrity monitoring on wp-content directory
3. Deploy intrusion detection signatures for PHP deserialization attacks
4. Conduct regular security audits of installed plugins for vulnerabilities
5. Maintain updated inventory of all plugins and their versions

Detection Rules:
1. Monitor for suspicious serialized object patterns in POST requests to admin endpoints
2. Alert on unexpected file modifications in wp-content/plugins directory
3. Track failed and successful administrator login attempts
4. Monitor for unusual PHP execution patterns or code execution attempts
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تدقيق جميع تثبيتات WordPress التي تستخدم إضافة LearnPress للنسخ الاحتياطي والترحيل
2. تقييد وصول حساب المسؤول للموظفين الموثوقين فقط
3. مراجعة وتوثيق جميع الإضافات والمواضيع المثبتة للبحث عن سلاسل POP المعروفة
4. تنفيذ قواعد جدار حماية تطبيقات الويب (WAF) للكشف عن أنماط الكائنات المسلسلة

إرشادات التصحيح:
1. تعطيل إضافة LearnPress للنسخ الاحتياطي والترحيل فوراً إذا لم تكن قيد الاستخدام النشط
2. مراقبة مستودع البائع للحصول على تصحيحات أمان (لا يوجد تصحيح متاح حالياً)
3. النظر في حلول بديلة للنسخ الاحتياطي بممارسات أمان أفضل
4. إذا كانت الإضافة حرجة، تنفيذ ضوابط وصول صارمة تحد من وصول المسؤول

الضوابط البديلة:
1. تفعيل إضافات أمان WordPress مع كشف حقن الكائنات
2. تنفيذ مراقبة سلامة الملفات في دليل wp-content
3. نشر توقيعات كشف التطفل لهجمات فك تسلسل PHP
4. إجراء تدقيقات أمان منتظمة للإضافات المثبتة للبحث عن الثغرات
5. الحفاظ على جرد محدث لجميع الإضافات وإصداراتها

قواعد الكشف:
1. مراقبة أنماط الكائنات المسلسلة المريبة في طلبات POST إلى نقاط نهاية المسؤول
2. التنبيه على تعديلات الملفات غير المتوقعة في دليل wp-content/plugins
3. تتبع محاولات تسجيل الدخول الفاشلة والناجحة للمسؤول
4. مراقبة أنماط تنفيذ PHP غير العادية أو محاولات تنفيذ الأكواد
