CVE-2025-66100 identifies a missing authorization vulnerability in the Magnigenie RestroPress plugin, specifically affecting versions up to 3.2.3.5. RestroPress is a WordPress plugin designed to facilitate online food ordering and restaurant management. The vulnerability stems from improperly configured access control mechanisms, allowing unauthorized users to bypass security checks and perform actions or access data that should be restricted. This type of flaw typically occurs when the application fails to verify user permissions before granting access to sensitive functions or data endpoints. Although no public exploits have been reported yet, the lack of authentication requirements for exploitation significantly raises the risk profile. Attackers could leverage this vulnerability to manipulate orders, access customer information, or disrupt restaurant operations. The absence of a CVSS score limits precise risk quantification, but the nature of the vulnerability suggests a high impact on confidentiality and integrity, with moderate impact on availability. Since RestroPress is widely used in the hospitality sector, especially by small and medium enterprises (SMEs) relying on WordPress, the vulnerability could have broad implications. The issue was reserved in late November 2025 and published in mid-December 2025, indicating recent discovery and disclosure. No patches or mitigations have been officially released at the time of this report, necessitating proactive defensive measures by affected organizations.

For European organizations, especially those in the hospitality and food service industries using RestroPress, this vulnerability poses a significant risk. Unauthorized access could lead to exposure of customer data, including personal and payment information, violating GDPR and other data protection regulations. Manipulation of orders or backend settings could disrupt business operations, causing financial losses and reputational damage. SMEs, which form a large part of the European hospitality sector, may lack dedicated security teams, increasing their vulnerability. The breach of confidentiality and integrity could also lead to regulatory penalties and loss of customer trust. Additionally, attackers might use compromised systems as footholds for further network intrusion. The lack of authentication requirement for exploitation broadens the attack surface, potentially allowing remote attackers to exploit the vulnerability without prior access. This elevates the threat level for organizations with externally accessible RestroPress installations.

Until an official patch is released, European organizations should implement specific mitigations: 1) Conduct a thorough audit of user roles and permissions within RestroPress to ensure minimal privileges are assigned. 2) Restrict access to the RestroPress administrative interfaces using network-level controls such as IP whitelisting or VPN access. 3) Employ Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized access attempts targeting RestroPress endpoints. 4) Monitor logs for unusual activity related to RestroPress, including unexpected API calls or changes to orders and settings. 5) Educate staff on the risks and encourage prompt reporting of suspicious behavior. 6) Plan for rapid deployment of patches once available, including testing in staging environments to avoid operational disruptions. 7) Consider temporarily disabling or limiting the plugin’s functionality if feasible, to reduce exposure. 8) Review and enhance overall WordPress security posture, including timely updates of all plugins and themes, and strong authentication mechanisms for administrative accounts.
