CVE-2025-13339 is a path traversal vulnerability categorized under CWE-22 found in the Hippoo Mobile App for WooCommerce WordPress plugin, affecting all versions up to and including 1.7.1. The vulnerability resides in the template_redirect() function, which improperly limits pathname access, allowing attackers to traverse directories and read arbitrary files on the server. This flaw can be exploited remotely without any authentication or user interaction, making it highly accessible to attackers. The ability to read arbitrary files can expose sensitive data such as configuration files, database credentials, or other private information stored on the server. The vulnerability has been assigned a CVSS 3.1 base score of 7.5, indicating a high severity due to its network attack vector, low attack complexity, no privileges required, and no user interaction needed, with a significant confidentiality impact but no impact on integrity or availability. Although no known exploits have been reported in the wild yet, the public disclosure and availability of technical details increase the risk of exploitation. The plugin is widely used in WooCommerce environments, which are popular in e-commerce websites, making this vulnerability a serious concern for online retailers. The lack of an official patch at the time of disclosure necessitates immediate mitigation steps to prevent exploitation. Monitoring and restricting access to the vulnerable plugin's endpoints and implementing web application firewall (WAF) rules can help reduce risk until a patch is released.

For European organizations, especially those operating e-commerce platforms using WooCommerce and the Hippoo Mobile App plugin, this vulnerability poses a significant risk of sensitive data exposure. Attackers can access configuration files, credentials, or other sensitive information that could facilitate further compromise or data breaches. This can lead to loss of customer trust, regulatory penalties under GDPR due to data exposure, and potential financial losses. The vulnerability's ease of exploitation and lack of authentication requirements make it particularly dangerous for small and medium enterprises that may lack advanced security monitoring. The impact extends to supply chain risks if attackers leverage exposed information to target connected systems. Given the critical role of e-commerce in European economies, especially in countries with high WooCommerce market penetration, the threat could disrupt business operations and damage reputations.

Immediate mitigation should focus on identifying all instances of the Hippoo Mobile App for WooCommerce plugin across the organization's WordPress infrastructure. Until an official patch is released, organizations should implement strict access controls to restrict access to the plugin's endpoints, particularly the template_redirect() function. Deploying Web Application Firewall (WAF) rules to detect and block path traversal patterns in HTTP requests can help prevent exploitation attempts. Regularly audit server logs for unusual file access or directory traversal attempts. Consider isolating or sandboxing the WordPress environment to limit the impact of potential breaches. Additionally, organizations should prepare to apply patches promptly once available and conduct thorough vulnerability scans to ensure no residual exposure. Educating web administrators about this vulnerability and encouraging immediate action is critical. Backup sensitive data and ensure recovery plans are in place in case of compromise.
