CVE-2026-24365 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Stock Manager for WooCommerce plugin, which is widely used to manage inventory within WooCommerce-based e-commerce websites. The vulnerability exists in all versions prior to 3.6.0, allowing attackers to craft malicious web requests that, when executed by an authenticated administrator, can perform unauthorized stock management actions such as modifying inventory levels or product availability. CSRF attacks exploit the trust a web application places in the user's browser by leveraging the user's authenticated session to perform unintended actions without their knowledge. Since the plugin lacks adequate anti-CSRF protections, such as synchronizer tokens or same-site cookie attributes, it is susceptible to these attacks. The vulnerability does not require any user interaction beyond visiting a malicious page while logged in, making exploitation relatively straightforward. Although no exploits have been reported in the wild yet, the potential impact on inventory integrity and business operations is significant, especially for e-commerce platforms relying on accurate stock data. The absence of a CVSS score indicates that the vulnerability is newly published and pending detailed scoring, but the technical characteristics suggest a high risk. The vulnerability affects the confidentiality and integrity of stock data and can disrupt availability if stock levels are manipulated maliciously. Patch releases or updates to the plugin should address this issue by implementing proper CSRF protections. Until patched, organizations should consider additional mitigations such as restricting administrative access, implementing web application firewalls (WAFs) with CSRF detection, and monitoring stock changes for anomalies.

For European organizations, particularly those operating e-commerce platforms using WooCommerce and the Stock Manager plugin, this vulnerability poses a risk of unauthorized manipulation of inventory data. Such unauthorized changes can lead to inaccurate stock levels, resulting in overselling, underselling, or stockouts, which directly impact revenue, customer satisfaction, and supply chain operations. The integrity of business-critical data is compromised, potentially causing financial losses and reputational damage. Additionally, attackers could leverage this vulnerability to disrupt operations by causing confusion in inventory management or triggering automated processes based on incorrect stock data. Given the widespread use of WooCommerce in Europe, especially among small to medium-sized enterprises (SMEs) in countries with mature e-commerce markets, the threat could affect a broad range of businesses. The lack of known exploits in the wild reduces immediate risk but does not eliminate the potential for targeted attacks. The vulnerability also increases the attack surface for more complex multi-stage attacks if combined with other weaknesses. Overall, the impact on confidentiality is moderate, but integrity and availability impacts are high due to the critical nature of inventory data in e-commerce operations.

1. Immediately update the Stock Manager for WooCommerce plugin to version 3.6.0 or later once the patch is available, as this will include proper CSRF protections. 2. Until patching is possible, restrict administrative access to trusted IP addresses and enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of session hijacking. 3. Implement Web Application Firewalls (WAFs) with rules to detect and block CSRF attack patterns targeting WooCommerce administrative endpoints. 4. Enable and enforce same-site cookie attributes (SameSite=Lax or Strict) to limit cross-origin requests from unauthorized sites. 5. Monitor stock management logs and audit trails closely for unusual or unauthorized changes to inventory data, enabling rapid detection and response. 6. Educate administrators about the risks of visiting untrusted websites while logged into the WooCommerce backend to reduce the likelihood of CSRF exploitation. 7. Consider deploying Content Security Policy (CSP) headers to restrict the sources of executable scripts and reduce the attack surface. 8. Regularly review and update security policies and plugin configurations to ensure compliance with best practices for web application security.
