CVE-2025-13339 is a path traversal vulnerability classified under CWE-22, found in the Hippoo Mobile App for WooCommerce plugin for WordPress. This vulnerability exists in all versions up to and including 1.7.1 and is exploitable via the template_redirect() function. The flaw arises due to improper limitation of pathname inputs, allowing attackers to manipulate file paths to access files outside the intended directory scope. This can be done without any authentication or user interaction, making it remotely exploitable over the network. Successful exploitation enables an attacker to read arbitrary files on the web server hosting the WordPress instance, potentially exposing sensitive information such as configuration files, database credentials, or private user data. The CVSS v3.1 base score is 7.5, reflecting a high severity due to the vulnerability's impact on confidentiality, ease of exploitation, and lack of required privileges. Although no public exploits have been reported yet, the vulnerability poses a significant risk to websites using this plugin, especially those handling sensitive e-commerce data. The lack of available patches at the time of publication increases the urgency for mitigation measures.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive business and customer information, including payment details, personal data, and internal configuration files. This exposure can result in reputational damage, regulatory penalties under GDPR for data breaches, and potential financial losses. E-commerce platforms relying on WooCommerce and the Hippoo Mobile App plugin are particularly vulnerable, as attackers could leverage the flaw to gain insights into backend systems or escalate further attacks. The breach of confidentiality could also facilitate targeted phishing or social engineering campaigns. Given the plugin's widespread use in small to medium-sized enterprises across Europe, the threat could affect a broad range of sectors including retail, finance, and healthcare. Additionally, the vulnerability could be exploited to gather intelligence for more complex attacks, increasing the overall risk landscape for affected organizations.

Organizations should immediately verify if they use the Hippoo Mobile App for WooCommerce plugin and upgrade to a patched version once available. In the absence of a patch, implement strict input validation and sanitization on all parameters processed by the template_redirect() function to prevent path traversal attempts. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious path traversal patterns. Restrict file system permissions to limit the web server’s access to only necessary directories, minimizing the impact of any unauthorized file reads. Regularly audit server logs for unusual access patterns or attempts to access sensitive files. Consider isolating WordPress instances in containerized or sandboxed environments to reduce lateral movement risks. Finally, maintain up-to-date backups and monitor threat intelligence feeds for emerging exploit information related to this CVE.
