CVE-2025-59578 is a vulnerability identified in the ShopMagic plugin for WooCommerce, a popular e-commerce automation tool developed by wpdesk. The issue is classified as an 'Insertion of Sensitive Information Into Sent Data' vulnerability, which allows an attacker to retrieve sensitive information embedded within data sent by the plugin. This vulnerability affects all versions up to and including 4.5.6. The vulnerability is exploitable remotely over the network without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The scope is 'changed' (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component, potentially impacting confidentiality. The CVSS score of 5.8 places it in the medium severity category. The vulnerability does not impact integrity or availability but compromises confidentiality by allowing unauthorized access to sensitive data. No known exploits have been reported in the wild, but the risk remains due to the ease of exploitation and the sensitive nature of the data involved. The vulnerability likely arises from improper handling or sanitization of sensitive information within the plugin's data transmission processes, possibly exposing customer or transactional data. Since ShopMagic integrates tightly with WooCommerce stores, exploitation could lead to leakage of customer details or business-sensitive information, which could be leveraged for further attacks or fraud.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the ShopMagic plugin, this vulnerability poses a risk of sensitive data leakage. The exposure of embedded sensitive information could include customer personal data, payment-related details, or internal business information, leading to privacy violations and potential non-compliance with GDPR regulations. Such data breaches can damage customer trust, result in financial penalties, and harm brand reputation. The medium severity indicates a moderate risk, but the lack of required authentication and user interaction increases the threat level, as attackers can remotely exploit the vulnerability without prior access. Organizations handling large volumes of e-commerce transactions or sensitive customer data are particularly vulnerable. Additionally, the confidentiality breach could facilitate secondary attacks such as phishing, identity theft, or targeted fraud against European customers. The impact is more pronounced in sectors with stringent data protection requirements and high customer trust expectations.

European organizations should immediately assess their use of the ShopMagic plugin and determine if they are running affected versions (up to 4.5.6). Since no patch links are currently provided, organizations should monitor wpdesk’s official channels for security updates and apply patches promptly once available. In the interim, consider disabling or limiting the use of ShopMagic features that handle sensitive data or restrict network access to the plugin’s endpoints via web application firewalls (WAFs) or network segmentation. Review and audit data flows within the WooCommerce environment to identify and minimize sensitive data exposure. Implement strict access controls and logging to detect any anomalous data retrieval attempts. Additionally, ensure that all WooCommerce and related plugins are kept up to date, and conduct regular vulnerability scans and penetration tests focusing on e-commerce data handling. Educate staff on recognizing signs of data leakage and enforce strong incident response procedures to quickly address any exploitation attempts.
