CVE-2026-24967 identifies a missing authorization vulnerability in the Amelia booking plugin (ameliabooking) for WordPress, affecting versions up to and including 1.2.38. The vulnerability arises from incorrectly configured access control security levels, which means that the plugin does not properly verify whether a user has the necessary permissions before allowing certain actions. This can lead to unauthorized users performing operations that should be restricted, such as viewing or modifying booking information or administrative settings. The lack of a CVSS score indicates that the vulnerability has not yet been fully assessed or scored, but the nature of missing authorization typically represents a significant security risk. No public exploits have been reported, suggesting that the vulnerability is either newly disclosed or not yet weaponized. Amelia is a popular WordPress plugin used for appointment and event booking management, making it a critical component for organizations relying on it for customer scheduling. The vulnerability could allow attackers to bypass intended access restrictions, potentially leading to unauthorized data disclosure, data manipulation, or disruption of booking services. The issue is confirmed by Patchstack and was published in early February 2026. Since no patch links are currently provided, organizations must monitor vendor communications closely for updates. The vulnerability affects the confidentiality and integrity of the booking data and could impact availability if exploited to disrupt services. Exploitation likely requires no authentication or minimal user privileges due to missing authorization checks, increasing the risk profile. The scope includes all installations running vulnerable versions of Amelia, which is widely used in Europe among small and medium enterprises, healthcare providers, and service industries. Immediate mitigation involves auditing access control configurations, restricting user permissions, and preparing to apply vendor patches once released.

For European organizations, the missing authorization vulnerability in Amelia can lead to unauthorized access to sensitive booking and scheduling data, which may include personal customer information, appointment details, and internal scheduling. This can result in confidentiality breaches, exposing private data to unauthorized parties. Integrity of the booking system can also be compromised if attackers modify or delete appointments, causing operational disruptions and loss of trust. In sectors like healthcare, legal services, or financial consulting, such disruptions could have severe consequences for client service and compliance with data protection regulations such as GDPR. The availability of booking services might be indirectly affected if attackers exploit the vulnerability to disrupt normal operations or cause denial of service through unauthorized actions. Since Amelia is integrated into WordPress sites, which are common in Europe, the attack surface is significant. Organizations relying on Amelia for customer interactions or internal scheduling must consider the risk of reputational damage and potential regulatory penalties if personal data is exposed. The absence of known exploits in the wild provides a window for proactive mitigation, but the ease of exploitation due to missing authorization elevates the threat level. Overall, the impact on European organizations ranges from data breaches and operational disruption to compliance risks and financial losses.

1. Immediately audit all Amelia plugin installations to identify versions at or below 1.2.38 and prioritize their update once a patch is released by the vendor. 2. Until a patch is available, restrict user roles and permissions within WordPress to the minimum necessary, especially limiting access to booking management functions. 3. Implement strict role-based access control (RBAC) policies to ensure that only authorized personnel can perform sensitive operations within Amelia. 4. Monitor logs and user activity for any unusual or unauthorized access attempts related to the booking system. 5. Consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting Amelia endpoints. 6. Educate administrative users about the vulnerability and the importance of not granting excessive permissions. 7. Regularly check the vendor’s official channels and security advisories for patch releases or additional guidance. 8. Conduct penetration testing focused on access control mechanisms within the booking system to identify any other potential weaknesses. 9. Backup booking data frequently to enable recovery in case of data manipulation or loss. 10. Review and enhance overall WordPress security posture, including plugin management and update policies, to reduce exposure to similar vulnerabilities.
