CVE-2025-68569 identifies a missing authorization vulnerability in the WP Time Slots Booking Form WordPress plugin developed by codepeople, affecting all versions up to and including 1.2.38. This vulnerability arises from incorrectly configured access control security levels, allowing attackers with low privileges (PR:L) to bypass authorization checks and perform unauthorized actions remotely over the network (AV:N) without requiring any user interaction (UI:N). The vulnerability impacts the confidentiality, integrity, and availability of the affected systems, as attackers can potentially manipulate booking data, access sensitive user information, or disrupt booking services. The CVSS v3.1 score of 8.8 (High) reflects the critical nature of this flaw, highlighting that exploitation is straightforward due to low attack complexity (AC:L) and no user interaction, with a scope limited to the vulnerable component (S:U). Although no known exploits are currently reported in the wild, the widespread use of WordPress and the popularity of booking plugins make this a significant threat. The vulnerability was published on December 24, 2025, and no official patches have been linked yet, emphasizing the need for vigilance and proactive mitigation by administrators. The flaw is particularly dangerous because booking forms often handle personal and payment data, making unauthorized access a serious privacy and operational risk.

For European organizations, especially those in the hospitality, healthcare, education, and service industries that rely heavily on online booking systems, this vulnerability poses a significant risk. Exploitation could lead to unauthorized data access, manipulation of booking schedules, disruption of services, and potential leakage of personal customer information, violating GDPR and other data protection regulations. The integrity and availability of booking services could be compromised, leading to operational downtime and reputational damage. Attackers could leverage this vulnerability to escalate privileges or pivot to other parts of the network, increasing the overall risk profile. The impact is heightened in organizations with insufficient internal access controls or those that have not segmented their WordPress environments adequately. Given the plugin’s integration with WordPress, a widely used CMS in Europe, the potential attack surface is large, increasing the likelihood of targeted attacks against vulnerable installations.

Organizations should immediately inventory their WordPress environments to identify installations of the WP Time Slots Booking Form plugin and verify the version in use. Until an official patch is released, restrict access to the plugin’s administrative and booking management interfaces by implementing strict IP whitelisting or VPN-only access. Employ Web Application Firewalls (WAF) with custom rules to detect and block suspicious requests targeting the plugin endpoints. Conduct thorough access control audits to ensure that only authorized users have the necessary privileges, and remove any unnecessary low-privilege accounts that could be exploited. Monitor logs for unusual activity related to booking form submissions or administrative actions. Consider temporarily disabling the plugin if it is not critical to operations. Once a patch is available, apply it promptly and test the environment to confirm the vulnerability is resolved. Additionally, educate staff about the risks and ensure backup and incident response plans are updated to handle potential exploitation scenarios.
