📄 Description (English)
The Amelia Booking plugin for WordPress is vulnerable to Insecure Direct Object References in versions up to, and including, 9.1.2. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers with customer-level permissions or above to change user passwords and potentially take over administrator accounts. The vulnerability is in the pro plugin, which has the same slug.

🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Audit all WordPress installations using Amelia Booking plugin versions ≤9.1.2 across your organization
2. Disable the Amelia Booking plugin immediately if not critical to operations, or restrict access to trusted administrators only
3. Review user access logs for suspicious password change activities, particularly targeting administrator accounts
4. Force password reset for all administrator and high-privilege accounts
5. Implement IP whitelisting to restrict plugin access to known administrative networks
COMPENSATING CONTROLS:
6. Implement Web Application Firewall (WAF) rules to block direct object reference attempts to user management endpoints
7. Deploy WordPress security plugins (Wordfence, Sucuri) with enhanced monitoring for unauthorized password changes
8. Enable WordPress user activity logging and set alerts for privilege escalation attempts
9. Restrict user roles — remove unnecessary customer-level accounts and enforce principle of least privilege
10. Implement multi-factor authentication (MFA) for all WordPress administrator accounts
DETECTION RULES:
11. Monitor WordPress database for unexpected password hash modifications in wp_users table
12. Alert on API calls to user management endpoints from non-administrative IP addresses
13. Track failed and successful authentication attempts to administrator accounts
14. Monitor for rapid successive user creation or role modification events
PATCHING:
15. Monitor Amelia Booking plugin repository for security updates; apply immediately upon release
16. Consider migrating to alternative booking solutions if patch timeline extends beyond 30 days
