CVE-2025-49510 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WPFactory Min Max Step Quantity Limits Manager plugin for WooCommerce, affecting versions up to 5.1.0. This plugin is used to enforce minimum, maximum, and step quantity limits on products in WooCommerce-based online stores. The vulnerability allows an attacker to trick an authenticated WooCommerce administrator or user with sufficient privileges into submitting unauthorized requests to the plugin, potentially altering quantity limit settings without their consent. The CVSS 3.1 base score is 4.3 (medium severity), reflecting that the attack vector is network-based (remote), requires no privileges, but does require user interaction (the victim must visit a malicious site). The impact is limited to integrity as the attacker can modify plugin settings, but confidentiality and availability are not affected. The vulnerability does not require authentication, but the victim must be logged in and interact with a crafted malicious webpage. No known exploits are currently reported in the wild, and no patches or updates have been linked yet. The issue stems from the lack of proper anti-CSRF tokens or validation mechanisms in the plugin's request handling, allowing unauthorized state-changing actions via forged requests. Given WooCommerce's widespread use in e-commerce, this vulnerability could be leveraged to disrupt store operations by manipulating product quantity constraints, potentially causing customer confusion, order processing errors, or inventory mismanagement.

For European organizations running WooCommerce stores with the vulnerable WPFactory plugin, this CSRF vulnerability poses a moderate risk. Attackers could exploit it to alter quantity limits on products, which may lead to incorrect order quantities being accepted or rejected, impacting sales and customer satisfaction. While it does not directly expose sensitive data or cause service outages, the integrity compromise can disrupt normal business operations and damage reputation. Small to medium-sized e-commerce businesses, which are prevalent across Europe, may be particularly vulnerable if they lack robust security awareness or patch management processes. Additionally, organizations in regulated sectors (e.g., retail, pharmaceuticals) could face compliance issues if manipulated product quantities affect contractual or legal obligations. The requirement for user interaction and an authenticated session limits the attack scope but does not eliminate risk, especially if employees or administrators are targeted via phishing or social engineering campaigns.

To mitigate this vulnerability, European WooCommerce store operators should: 1) Immediately verify if their installations use the WPFactory Min Max Step Quantity Limits Manager plugin and identify the version. 2) Monitor the vendor's official channels for patches or updates addressing CVE-2025-49510 and apply them promptly once available. 3) In the interim, restrict administrative access to trusted networks or VPNs to reduce exposure to CSRF attacks. 4) Implement web application firewalls (WAFs) with custom rules to detect and block suspicious cross-site requests targeting the plugin's endpoints. 5) Educate administrators and users about phishing and social engineering risks to prevent inadvertent interaction with malicious sites. 6) Review and harden WooCommerce and WordPress security configurations, including enforcing strong session management and limiting user privileges to the minimum necessary. 7) Consider disabling or replacing the vulnerable plugin if a timely patch is not forthcoming, to eliminate the attack surface. These steps go beyond generic advice by focusing on access controls, monitoring, and user awareness tailored to the specific vulnerability context.
