CVE-2025-68027 is an Incorrect Privilege Assignment vulnerability found in the Themefic Hydra Booking plugin, versions up to 1.1.32. This flaw allows an unauthenticated remote attacker to escalate privileges within the affected system by exploiting improper access control mechanisms. Specifically, the plugin fails to correctly enforce privilege checks on certain functions or API endpoints, enabling attackers to perform actions reserved for higher-privileged users. The vulnerability is remotely exploitable over the network without requiring any user interaction or prior authentication, increasing its risk profile. The CVSS v3.1 base score is 7.3, reflecting the ease of exploitation (attack vector: network, low attack complexity), no privileges required, and no user interaction needed. The impact affects confidentiality, integrity, and availability, though to a limited extent (partial loss). No known public exploits or patches are currently available, but the vulnerability is publicly disclosed and assigned a CVE identifier. Hydra Booking is a WordPress plugin used for booking and appointment management, often deployed by businesses and organizations to handle scheduling. The incorrect privilege assignment could allow attackers to manipulate bookings, access sensitive user data, or disrupt service availability by escalating their privileges within the plugin or WordPress environment.

For European organizations, the impact of CVE-2025-68027 can be significant, especially for those relying on Hydra Booking for customer-facing scheduling services. Successful exploitation could lead to unauthorized access to booking data, manipulation or deletion of appointments, and potential exposure of personally identifiable information (PII) of clients. This undermines data confidentiality and integrity, potentially violating GDPR requirements. Additionally, attackers could disrupt service availability, harming business operations and reputation. Organizations in sectors such as healthcare, hospitality, education, and professional services that use this plugin are particularly at risk. The vulnerability's remote exploitability without authentication increases the likelihood of attacks, including automated scanning and exploitation attempts. Although no active exploits are reported, the public disclosure and high CVSS score suggest that threat actors may develop exploits soon, increasing urgency for mitigation. The impact extends beyond direct data compromise to regulatory, financial, and reputational consequences for affected European entities.

Given the absence of an official patch at the time of this report, European organizations should implement immediate compensating controls. These include restricting network access to the WordPress administration interface and plugin endpoints via firewalls or VPNs, limiting exposure to trusted IP addresses only. Implement strict role-based access controls within WordPress to minimize privileges assigned to users and plugins. Monitor logs for unusual activities related to Hydra Booking plugin endpoints or privilege escalations. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting known vulnerable functions. Regularly back up booking data and WordPress configurations to enable rapid recovery in case of compromise. Stay informed on vendor announcements for patches or updates and apply them promptly once available. Conduct security audits and vulnerability scans focusing on WordPress plugins to identify similar privilege issues. Educate administrators and users about the risks of using outdated plugins and the importance of timely updates.
