CVE-2025-68575 identifies a missing authorization vulnerability in the Wappointment plugin developed by the Wappointment team, affecting versions up to and including 2.7.2. The core issue stems from incorrectly configured access control security levels, which means that certain functions or data within the plugin can be accessed or manipulated without proper permission checks. This type of vulnerability typically arises when the application fails to verify whether a user has the necessary rights before allowing an action, leading to unauthorized access. Wappointment is a WordPress plugin commonly used for appointment scheduling, and such a vulnerability could allow attackers to bypass restrictions, potentially viewing or modifying appointment data, user information, or administrative settings. Although no public exploits have been reported yet, the nature of missing authorization vulnerabilities makes them attractive targets for attackers, as they often require no authentication or minimal user interaction. The absence of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the technical details suggest a significant risk. The vulnerability was reserved on December 19, 2025, and published shortly after, indicating recent discovery. The lack of available patches at the time of publication means that organizations must rely on interim controls until official fixes are released.

For European organizations, the impact of this vulnerability can be substantial, especially for those relying on Wappointment for managing sensitive appointment data, such as healthcare providers, legal firms, or government services. Unauthorized access could lead to exposure of personal data protected under GDPR, resulting in legal and financial consequences. Integrity of appointment schedules could be compromised, disrupting business operations and causing reputational damage. Since Wappointment is a WordPress plugin, organizations using WordPress-based websites are at risk, and given the widespread use of WordPress across Europe, the scope is broad. The vulnerability could also be leveraged as a foothold for further attacks within the network if attackers gain administrative privileges. The lack of authentication requirements for exploitation increases the risk, as attackers can potentially exploit the flaw remotely without user interaction. This elevates the threat level and necessitates urgent attention from affected organizations.

Organizations should immediately audit their Wappointment plugin versions and confirm if they are running version 2.7.2 or earlier. Until an official patch is released, it is critical to implement compensating controls such as restricting access to the plugin’s administrative interfaces via IP whitelisting or VPNs. Employing a Web Application Firewall (WAF) with custom rules to detect and block unauthorized access attempts targeting Wappointment endpoints can reduce risk. Review and tighten user roles and permissions within WordPress to ensure least privilege principles are enforced. Monitoring logs for unusual access patterns related to Wappointment functions can help detect exploitation attempts early. Organizations should subscribe to vendor notifications and security advisories to apply patches promptly once available. Additionally, consider isolating the affected systems or limiting their network exposure to reduce attack surface. Regular backups of appointment data should be maintained to enable recovery in case of data tampering.
