CVE-2025-53424 is a missing authorization vulnerability found in the vanquish WooCommerce Orders & Customers Exporter plugin, versions up to and including 5.4. This plugin is designed to export order and customer data from WooCommerce, a popular e-commerce platform for WordPress. The vulnerability arises due to improperly configured access control mechanisms, allowing unauthenticated remote attackers to bypass authorization checks and export sensitive data without any privileges. The CVSS v3.1 base score is 6.5 (medium severity), reflecting that the attack vector is network-based (AV:N), requires no privileges (PR:N), and no user interaction (UI:N), with impacts on confidentiality (C:L) and integrity (I:L), but no impact on availability (A:N). The flaw could lead to unauthorized disclosure and potential manipulation of order and customer information, which may include personally identifiable information (PII), payment details, and order histories. Although no public exploits have been reported yet, the vulnerability’s nature makes it a significant risk for e-commerce sites relying on this plugin. The lack of patches at the time of reporting means organizations must implement interim controls to limit exposure. The vulnerability was reserved in June 2025 and published in October 2025, indicating recent discovery and disclosure.

For European organizations, the impact of CVE-2025-53424 is primarily the unauthorized disclosure and potential alteration of sensitive customer and order data. This can lead to privacy violations under GDPR, reputational damage, financial losses from fraud or chargebacks, and regulatory penalties. E-commerce businesses using WooCommerce with the affected plugin are at risk of data breaches that compromise customer trust and operational integrity. The medium severity score reflects moderate risk but given the sensitivity of customer data, the consequences can be significant. The vulnerability’s exploitation does not affect system availability but can undermine data confidentiality and integrity, potentially enabling further attacks such as identity theft or targeted phishing. Organizations with large customer bases or handling sensitive payment information are particularly vulnerable. The absence of required authentication lowers the barrier for attackers, increasing the likelihood of exploitation if unmitigated.

1. Apply vendor patches immediately once they become available to address the missing authorization controls. 2. Until patches are released, restrict access to the WooCommerce Orders & Customers Exporter plugin’s export functionality by limiting network access via firewalls or IP whitelisting to trusted administrators only. 3. Implement strict role-based access controls within WordPress and WooCommerce to ensure only authorized users can access export features. 4. Monitor logs for unusual or large export requests that could indicate exploitation attempts. 5. Consider disabling or uninstalling the plugin if export functionality is not essential. 6. Conduct regular security audits and vulnerability scans focused on WordPress plugins. 7. Educate administrators on the risks of unauthorized data exports and enforce strong authentication mechanisms for backend access. 8. Use web application firewalls (WAF) to detect and block suspicious requests targeting the plugin’s endpoints. 9. Maintain up-to-date backups to recover quickly in case of data integrity issues. 10. Review and enhance overall e-commerce security posture, including GDPR compliance measures.
