CVE-2025-9029 is a medium-severity vulnerability identified in the WDesignKit plugin for WordPress, which is used to provide Elementor and Gutenberg starter templates, patterns, cloud workspace, and widget building capabilities. The vulnerability stems from a missing authorization check in the function wdkit_handle_review_submission in versions up to and including 1.2.16. Specifically, the plugin fails to properly verify whether a user is authorized to perform the action of submitting feedback data. This flaw allows unauthenticated attackers to submit arbitrary feedback data to external services via the plugin. The vulnerability is classified under CWE-862 (Missing Authorization), indicating that the system does not correctly enforce access control policies. The CVSS 3.1 base score is 4.3, reflecting a medium severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), no impact on confidentiality (C:N), limited impact on integrity (I:L), and no impact on availability (A:N). Although exploitation does not require user interaction, it does require some level of privileges, which suggests that the attacker must have some authenticated access, but the description also mentions unauthenticated attackers can exploit it, indicating a possible discrepancy or that the privilege requirement is minimal or misclassified. The vulnerability does not appear to have known exploits in the wild yet, and no patches have been linked, indicating that mitigation may require vendor updates or manual intervention. The risk primarily involves integrity, as unauthorized feedback submissions could be used to manipulate external services or data flows, potentially leading to misinformation or abuse of integrated feedback mechanisms.

For European organizations, especially those relying on WordPress websites with the WDesignKit plugin installed, this vulnerability could lead to unauthorized submission of feedback data to external services, potentially undermining data integrity and trustworthiness of user-generated content or feedback systems. This could be exploited to inject misleading or malicious data, which might affect customer perception, analytics, or automated processes relying on feedback. While the vulnerability does not directly compromise confidentiality or availability, the integrity impact could have reputational consequences and might be leveraged as part of a broader attack chain. Organizations in sectors such as e-commerce, media, or public services that use WordPress extensively could face risks of data pollution or manipulation. Additionally, if external services receiving feedback are critical or sensitive, unauthorized submissions could trigger further security or operational issues. Given the medium severity and lack of known exploits, the immediate risk is moderate, but the potential for abuse exists, especially if combined with other vulnerabilities or social engineering tactics.

European organizations should first identify if their WordPress installations use the WDesignKit plugin, particularly versions up to 1.2.16. Since no official patches are linked yet, organizations should consider the following specific mitigations: 1) Temporarily disable or remove the WDesignKit plugin until a security update is released. 2) Implement web application firewall (WAF) rules to monitor and block unauthorized requests targeting the wdkit_handle_review_submission endpoint or related AJAX calls. 3) Restrict access to feedback submission endpoints by IP whitelisting or authentication enforcement at the web server or application level. 4) Monitor logs for unusual or unauthorized feedback submission attempts to detect exploitation attempts early. 5) Engage with the plugin vendor or community to obtain or expedite security patches. 6) Educate site administrators about the risk and ensure minimal privilege principles are applied to user roles to reduce the chance of privilege escalation. 7) Review and audit external services receiving feedback data to validate and sanitize incoming data to prevent downstream impact. These targeted actions go beyond generic advice by focusing on the specific vulnerable function and plugin behavior.
