CVE-2025-54029 is a high-severity path traversal vulnerability (CWE-22) found in the 'WooCommerce csv import export' plugin developed by extendons. This vulnerability allows an attacker with at least low-level privileges (PR:L) and no user interaction (UI:N) to exploit improper limitation of pathnames to restricted directories. Specifically, the flaw enables an attacker to manipulate file paths during CSV import/export operations, potentially accessing or overwriting files outside the intended directory scope. The vulnerability affects all versions up to 2.0.6. The CVSS 3.1 base score of 7.7 reflects a network attack vector (AV:N), low attack complexity (AC:L), and a scope change (S:C), indicating that the vulnerability can impact resources beyond the initially vulnerable component. Although confidentiality and integrity impacts are rated as none (C:N, I:N), the availability impact is high (A:H), meaning exploitation could lead to denial of service or disruption of the import/export functionality, possibly affecting business operations relying on WooCommerce data management. No known exploits are currently reported in the wild, and no patches have been linked yet, suggesting that mitigation may require vendor updates or manual intervention. The vulnerability is particularly concerning because WooCommerce is a widely used e-commerce platform plugin for WordPress, and the CSV import/export functionality is critical for bulk product and order management. Improper path validation could allow attackers to overwrite or delete critical files, disrupt service, or cause data loss.

For European organizations using WooCommerce with the vulnerable csv import export plugin, this vulnerability poses a significant risk to the availability of their e-commerce operations. Disruption of import/export processes can delay product updates, inventory management, and order processing, leading to financial losses and customer dissatisfaction. Although confidentiality and integrity are not directly impacted, the availability impact can indirectly affect business continuity and trust. Organizations handling sensitive customer or transactional data may face operational downtime, which could also trigger regulatory scrutiny under GDPR if service disruptions affect data processing obligations. Given the network attack vector and low complexity, attackers could exploit this vulnerability remotely if they have low-level access, such as a compromised user account or a misconfigured system, making it a realistic threat in multi-user or shared hosting environments common in Europe. The lack of known exploits currently reduces immediate risk but does not eliminate the potential for future attacks once exploit code becomes available.

European organizations should immediately audit their WooCommerce installations to identify if the vulnerable 'WooCommerce csv import export' plugin version 2.0.6 or earlier is in use. Until an official patch is released, organizations should consider disabling the CSV import/export functionality or restricting access to trusted users only, minimizing the attack surface. Implement strict file system permissions on the server to prevent unauthorized file modifications outside designated directories. Monitoring and logging file access related to WooCommerce import/export operations can help detect suspicious activity. Additionally, applying web application firewall (WAF) rules to detect and block path traversal patterns in HTTP requests can provide a layer of defense. Organizations should subscribe to vendor advisories for timely patch releases and test updates in staging environments before deployment. Regular backups of WooCommerce data and configuration files are essential to enable quick recovery in case of exploitation. Finally, review user privileges to ensure only necessary users have import/export capabilities, reducing the risk of insider threats or compromised accounts being leveraged.
