CVE-2025-47451 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WordPress plugin 'Product Quantity Dropdown For Woocommerce' developed by silverplugins217. This plugin is designed to enhance WooCommerce stores by allowing customers to select product quantities via a dropdown interface. The vulnerability affects all versions up to 1.2. 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, without their consent or knowledge. In this case, the vulnerability allows an attacker to craft malicious requests that can alter the product quantity selections on a WooCommerce store without the user's intention. The CVSS v3.1 base score is 4.3 (medium severity), with the vector indicating that the attack can be performed remotely over the network (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The impact is limited to integrity (I:L), with no impact on confidentiality or availability. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability is classified under CWE-352, which specifically relates to CSRF issues. Since WooCommerce is a widely used e-commerce platform, plugins like this one are often installed on many online stores, making the vulnerability relevant to e-commerce operators using this plugin. The attack scenario typically involves an attacker luring a logged-in user (such as a store administrator or customer) to a malicious website or sending a crafted link that triggers unintended changes to product quantity selections, potentially disrupting order processing or inventory management.

For European organizations operating WooCommerce-based e-commerce stores with the affected 'Product Quantity Dropdown For Woocommerce' plugin installed, this vulnerability poses a moderate risk to the integrity of their online sales processes. An attacker exploiting this CSRF flaw could manipulate product quantities in customer carts or orders without authorization, potentially leading to incorrect order fulfillment, inventory discrepancies, or customer dissatisfaction. While the vulnerability does not directly expose sensitive data or cause service outages, the integrity impact can translate into financial losses, reputational damage, and operational disruptions. This is particularly significant for small to medium-sized enterprises (SMEs) that rely heavily on WooCommerce for their online sales and may lack advanced security monitoring. Additionally, if exploited against administrative users, attackers might alter product quantities in backend order management, complicating order processing workflows. Given the medium CVSS score and the requirement for user interaction, the threat is less severe than remote code execution vulnerabilities but still warrants attention to prevent exploitation in targeted phishing or social engineering campaigns.

To mitigate this vulnerability, European organizations should take the following specific actions: 1) Immediately review and monitor the usage of the 'Product Quantity Dropdown For Woocommerce' plugin across their WooCommerce installations. 2) Since no patch is currently available, consider temporarily disabling or uninstalling the plugin until a secure update is released. 3) Implement or enforce anti-CSRF tokens and nonce verification mechanisms in all forms and AJAX requests related to product quantity changes to ensure that requests originate from legitimate users and sessions. 4) Educate users, especially administrators and frequent customers, about the risks of phishing and social engineering attacks that could trigger CSRF exploits, emphasizing cautious behavior when clicking on links or visiting untrusted websites. 5) Employ web application firewalls (WAFs) with rules designed to detect and block suspicious CSRF attack patterns targeting WooCommerce plugins. 6) Monitor logs for unusual activity related to product quantity changes or order modifications that could indicate exploitation attempts. 7) Stay informed about updates from the plugin vendor or security advisories to apply patches promptly once available. These steps go beyond generic advice by focusing on plugin-specific controls, user awareness, and proactive monitoring tailored to the e-commerce context.
