CVE-2025-54674 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the mklacroix Product Configurator plugin for WooCommerce, affecting versions up to and including 1.4.4. CSRF vulnerabilities allow an attacker to trick 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 exists because the plugin does not adequately verify the origin or intent of requests that modify product configurations. The CVSS 3.1 base score of 5.4 (medium severity) reflects that the vulnerability can be exploited remotely over the network without authentication (AV:N, PR:N), but requires user interaction (UI:R), and impacts integrity and availability (I:L, A:L) without compromising confidentiality (C:N). Exploitation could allow an attacker to alter product configurations or disrupt the normal operation of the WooCommerce product configurator, potentially leading to incorrect product options being presented or orders being manipulated. Although no known exploits are currently reported in the wild, the vulnerability poses a risk especially for e-commerce sites relying on this plugin for product customization. The lack of a patch link suggests that a fix may not yet be publicly available, emphasizing the need for immediate mitigation steps.

For European organizations operating e-commerce platforms using WooCommerce with the mklacroix Product Configurator plugin, this vulnerability could lead to unauthorized manipulation of product configurations. This may result in customer dissatisfaction, loss of sales, or reputational damage if incorrect product options are offered or orders are processed incorrectly. Additionally, attackers could disrupt availability by causing errors or misconfigurations. While the vulnerability does not directly expose sensitive customer data, the integrity and availability impacts could indirectly affect business operations and customer trust. Given the widespread use of WooCommerce in Europe, especially among small and medium-sized enterprises (SMEs), the threat could affect a significant number of online retailers. Compliance with EU regulations such as the GDPR also means that any disruption or manipulation affecting customer transactions must be managed carefully to avoid regulatory scrutiny.

To mitigate this CSRF vulnerability, organizations should implement the following specific measures: 1) Immediately review and apply any available updates or patches from the mklacroix vendor once released. 2) If no patch is available, temporarily disable or replace the Product Configurator plugin with alternative solutions that have proper CSRF protections. 3) Implement web application firewalls (WAFs) with rules to detect and block suspicious CSRF attempts targeting WooCommerce endpoints. 4) Enforce strict SameSite cookie attributes (SameSite=Lax or Strict) to reduce the risk of CSRF attacks via cross-origin requests. 5) Validate and verify anti-CSRF tokens on all state-changing requests within the WooCommerce environment. 6) Educate users and administrators about the risks of CSRF and encourage cautious behavior regarding unsolicited links or emails. 7) Monitor logs for unusual activity related to product configuration changes to detect potential exploitation attempts early.
