CVE-2025-26764 identifies a missing authorization vulnerability in the enituretechnology Distance Based Shipping Calculator plugin, which is used primarily in e-commerce platforms to calculate shipping costs based on distance. The vulnerability stems from incorrectly configured access control security levels, meaning that certain functions or data within the plugin can be accessed without proper authorization checks. This misconfiguration can allow unauthorized users, including unauthenticated attackers or users with limited privileges, to exploit the plugin’s functionalities beyond their intended scope. The affected versions include all releases up to and including 2.0.22. The absence of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed by standard scoring bodies. The vulnerability does not currently have known exploits in the wild, but the potential for unauthorized access or manipulation of shipping calculations could impact order processing, pricing integrity, and customer trust. The plugin’s role in calculating shipping costs means that exploitation could lead to financial discrepancies or denial of service conditions if attackers manipulate shipping parameters or disrupt normal operations. The root cause is a failure to enforce proper authorization checks on sensitive operations within the plugin, a common security oversight in web applications. Given the plugin’s deployment in e-commerce environments, the vulnerability could be leveraged to gain unauthorized access to shipping data or interfere with order fulfillment processes.

The primary impact of CVE-2025-26764 is the potential unauthorized access to or manipulation of shipping calculation data within e-commerce platforms using the affected plugin. This can lead to financial losses due to incorrect shipping charges, exploitation of shipping cost calculations, or disruption of order processing workflows. Attackers might exploit this vulnerability to bypass restrictions, potentially altering shipping parameters or accessing sensitive operational data. This undermines the integrity and availability of the shipping calculation service, potentially damaging customer trust and causing operational disruptions. For organizations worldwide, especially those relying heavily on automated shipping calculations, this could translate into revenue loss, increased customer service overhead, and reputational damage. The lack of authentication or authorization enforcement increases the ease of exploitation, broadening the scope of affected systems. Although no active exploits are reported, the vulnerability’s presence in a widely used plugin makes it a significant risk vector for attackers targeting e-commerce infrastructure.

Organizations should immediately audit their use of the enituretechnology Distance Based Shipping Calculator plugin and restrict access to its administrative and functional interfaces to trusted users only. Until an official patch is released, implement web application firewall (WAF) rules to block unauthorized attempts to access or manipulate the plugin’s endpoints. Review and harden access control configurations within the plugin settings and the hosting platform to ensure that only authorized users can invoke sensitive functions. Monitor logs for unusual access patterns or attempts to exploit shipping calculation features. Engage with the vendor or plugin maintainers to obtain updates or patches addressing the missing authorization issue. Additionally, consider isolating the plugin’s functionality within segmented network zones to limit potential lateral movement in case of exploitation. Regularly update all e-commerce platform components and plugins to their latest versions to reduce exposure to known vulnerabilities.
