CVE-2026-25368 identifies a Missing Authorization vulnerability in the codepeople Calculated Fields Form WordPress plugin, affecting versions up to 5.4.4.1. The vulnerability stems from improperly configured access control security levels, which fail to enforce authorization checks on certain plugin functionalities. This allows an attacker, potentially without authentication, to access or manipulate calculated fields that should be restricted to authorized users only. Calculated Fields Form is a plugin used to create dynamic forms with calculated values, often employed in business websites for data collection and processing. The lack of authorization can lead to unauthorized data modification, injection of malicious input, or exposure of sensitive information handled by the forms. Although no known exploits have been reported in the wild, the vulnerability is publicly disclosed and could be targeted by attackers once exploit code becomes available. No official patches or updates are currently linked, indicating that users must monitor vendor advisories closely. The absence of a CVSS score requires an assessment based on the vulnerability’s characteristics: it affects confidentiality and integrity, can be exploited without authentication, and impacts a widely used plugin, increasing the risk profile. Organizations relying on this plugin should evaluate their exposure and prioritize remediation to prevent unauthorized access or data breaches.

For European organizations, the impact of CVE-2026-25368 can be significant, particularly for those using the Calculated Fields Form plugin on WordPress sites handling sensitive or regulated data. Unauthorized access to form calculations can lead to data integrity issues, manipulation of business logic, and potential leakage of confidential information. This can undermine trust, cause compliance violations (e.g., GDPR), and disrupt business operations. Attackers exploiting this vulnerability could alter form outputs, inject malicious data, or gain footholds for further attacks within the network. The risk is heightened for sectors such as finance, healthcare, and e-commerce, where data accuracy and confidentiality are critical. Additionally, the lack of authentication requirements lowers the barrier for exploitation, increasing the likelihood of attacks. The absence of patches means organizations must implement interim controls to mitigate risk. Overall, the vulnerability threatens confidentiality and integrity, with possible indirect impacts on availability if exploited to compromise site functionality.

1. Monitor the vendor’s official channels and security advisories for patches or updates addressing CVE-2026-25368 and apply them immediately upon release. 2. Conduct a thorough audit of user roles and permissions within WordPress to ensure that only trusted administrators have access to the Calculated Fields Form plugin settings and functionalities. 3. Implement web application firewalls (WAF) with custom rules to detect and block unauthorized attempts to access or manipulate calculated fields. 4. Restrict access to the WordPress admin interface by IP whitelisting or VPN to limit exposure to trusted networks. 5. Review and harden the plugin’s configuration, disabling any unnecessary features that could be exploited. 6. Regularly monitor logs for suspicious activity related to form submissions or plugin usage. 7. Educate site administrators about the risks and signs of exploitation to enable rapid detection and response. 8. Consider temporary removal or replacement of the plugin if immediate patching is not feasible and the risk is high.
