CVE-2025-58804 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the brijrajs WooCommerce Single Page Checkout plugin, affecting versions up to 1.2.7. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting unwanted actions on a web application in which they are currently authenticated. In this case, the vulnerability exists because the plugin does not adequately verify the origin of requests that perform sensitive operations during the checkout process. An attacker could craft a malicious web page or email that, when visited or clicked by a logged-in user of a WooCommerce store using this plugin, could cause unintended actions such as modifying checkout parameters or submitting fraudulent orders without the user’s consent. The CVSS 3.1 base score of 4.3 (medium severity) reflects that the attack vector is network-based (remote), requires no privileges, but does require user interaction (the victim must visit a malicious page). The impact is limited to integrity, with no confidentiality or availability impact. There are no known exploits in the wild at the time of publication, and no patches have been linked yet. The vulnerability is classified under CWE-352, which is a common web application security weakness related to insufficient request validation to prevent CSRF attacks. WooCommerce Single Page Checkout is a plugin used to streamline the checkout process on WooCommerce-based e-commerce sites, which are widely used on WordPress platforms globally. This vulnerability could allow attackers to manipulate checkout workflows, potentially leading to fraudulent transactions or manipulation of order data.

For European organizations operating e-commerce websites using WooCommerce with the affected Single Page Checkout plugin, this vulnerability poses a risk of unauthorized manipulation of checkout processes. While the confidentiality of customer data is not directly compromised, the integrity of transaction data can be affected, potentially leading to financial losses, order fraud, or disruption of business operations. This can damage customer trust and lead to reputational harm. Since WooCommerce is widely adopted across Europe, especially by small and medium-sized enterprises (SMEs) in retail and services sectors, the risk is significant for organizations that have not updated or mitigated this vulnerability. Attackers could exploit this vulnerability to submit fraudulent orders or alter order details without the knowledge of the user or the merchant. The lack of known exploits currently limits immediate risk, but the public disclosure increases the likelihood of future exploitation attempts. Regulatory compliance such as GDPR may also be indirectly impacted if fraudulent transactions lead to customer complaints or data handling issues.

Specific mitigation steps include: 1) Immediate review and update of the WooCommerce Single Page Checkout plugin to the latest version once a patch is released by the vendor. 2) In the absence of a patch, implement additional CSRF protections at the web application or server level, such as enforcing strict SameSite cookie attributes, validating CSRF tokens on all state-changing requests, and verifying the HTTP Referer or Origin headers. 3) Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious CSRF attack patterns targeting checkout endpoints. 4) Educate users and administrators about the risks of CSRF and encourage cautious behavior regarding unsolicited links or emails. 5) Conduct regular security audits and penetration testing focusing on e-commerce workflows to detect similar vulnerabilities. 6) Monitor logs for unusual checkout activity that could indicate exploitation attempts. These measures go beyond generic advice by focusing on compensating controls and proactive monitoring until an official patch is available.
