CVE-2025-66100 identifies a missing authorization vulnerability in Magnigenie RestroPress, a restaurant management and ordering plugin widely used for online food ordering systems. The vulnerability exists due to improperly configured access control mechanisms that fail to verify whether a user has the necessary permissions to perform certain actions. This allows an attacker with low privileges (PR:L) to execute unauthorized operations that can alter data integrity (I:H) without impacting confidentiality or availability. The attack vector is network-based (AV:N), and no user interaction is required (UI:N), making it feasible for remote exploitation. The affected versions include all releases up to and including 3.2.3.5. Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk because it can be leveraged to manipulate order data, pricing, or other critical business information within the RestroPress system. The lack of patches at the time of publication necessitates immediate attention to access control configurations and monitoring for suspicious activities. The vulnerability's CVSS 3.1 score of 6.5 reflects a medium severity, primarily due to the ease of exploitation and the high impact on data integrity.

For European organizations, particularly those in the hospitality and food service sectors relying on RestroPress for online ordering and restaurant management, this vulnerability can lead to unauthorized modification of orders, pricing, or customer data. This compromises the integrity of business operations, potentially causing financial losses, customer dissatisfaction, and reputational damage. Since the vulnerability does not affect confidentiality or availability, data breaches or service outages are less likely; however, manipulated order data can disrupt supply chains and financial reconciliation processes. The medium severity and network exploitability mean attackers can remotely target these systems without user interaction, increasing the risk of automated or large-scale attacks. Organizations with integrated e-commerce platforms or third-party payment systems may face cascading effects if order data is altered. Regulatory compliance risks may also arise if manipulated data affects financial reporting or customer transaction records.

Organizations should immediately review and tighten access control policies within RestroPress, ensuring that all sensitive operations require proper authorization checks. Until an official patch is released, administrators can implement compensating controls such as restricting RestroPress administrative access to trusted IP addresses or VPNs, enabling detailed logging and monitoring of user actions to detect unauthorized attempts, and conducting regular audits of user permissions. It is also advisable to isolate RestroPress installations from other critical systems to limit potential lateral movement. Once patches become available from Magnigenie, prompt application is essential. Additionally, organizations should educate staff about the risks of privilege misuse and enforce the principle of least privilege for all users. Network-level protections such as web application firewalls (WAFs) can be tuned to detect and block suspicious requests targeting RestroPress endpoints. Finally, maintaining up-to-date backups will aid in recovery if data integrity is compromised.
