CVE-2025-58799 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the themelocation Custom WooCommerce Checkout Fields Editor plugin, affecting versions up to 1.3.4. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application in which they are currently authenticated, potentially causing unintended actions without the user's consent. In this case, the vulnerability allows an attacker to perform unauthorized state-changing operations within the WooCommerce checkout fields editor by exploiting the lack of proper CSRF protections such as anti-CSRF tokens or referer validation. The vulnerability is classified under CWE-352, which specifically addresses CSRF issues. The CVSS v3.1 base score is 4.3 (medium severity), with the vector indicating that the attack can be performed remotely (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The impact is limited to integrity (I:L), with no confidentiality or availability impact. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. The plugin is used to customize WooCommerce checkout fields, which is a common e-commerce platform plugin for WordPress, widely used to tailor checkout experiences. The vulnerability could allow attackers to manipulate checkout field configurations, potentially disrupting business processes or causing customer confusion, but does not directly expose sensitive data or cause denial of service.

For European organizations using WooCommerce with the themelocation Custom WooCommerce Checkout Fields Editor plugin, this vulnerability could lead to unauthorized modification of checkout field configurations. While it does not directly compromise customer data confidentiality or availability of services, it can undermine the integrity of the e-commerce checkout process. This could result in incorrect or maliciously altered checkout fields, potentially causing transaction errors, loss of customer trust, or financial discrepancies. Given the widespread adoption of WooCommerce in Europe, especially among small and medium-sized enterprises (SMEs) in retail and services sectors, the threat could disrupt online sales operations. Additionally, altered checkout fields might be used to mislead customers or interfere with payment processes, indirectly impacting compliance with European consumer protection regulations and GDPR if personal data handling is affected. However, the requirement for user interaction (the victim must be authenticated and perform an action) limits the ease of exploitation, reducing the immediate risk of large-scale automated attacks.

European organizations should prioritize the following mitigations: 1) Immediately verify if the installed version of the themelocation Custom WooCommerce Checkout Fields Editor plugin is affected (version 1.3.4 or earlier) and monitor for official patches or updates from the vendor. 2) If no patch is available, consider temporarily disabling or removing the plugin to prevent exploitation. 3) Implement web application firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the plugin’s endpoints. 4) Enforce strict user session management and ensure users log out after completing sensitive operations to reduce the window of opportunity for CSRF attacks. 5) Educate administrators and users about the risks of CSRF and encourage cautious behavior regarding unsolicited links or actions while logged into administrative accounts. 6) Review and harden the WooCommerce and WordPress environment by enabling security plugins that add CSRF protections or nonce verification for critical actions. 7) Conduct regular security audits and penetration testing focused on plugin vulnerabilities and CSRF vectors.
