CVE-2025-54030 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the GSheetConnector by WesternDeal, specifically affecting the WooCommerce Google Sheet Connector plugin versions up to 1.3.20. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application, causing the application to perform unwanted actions on behalf of the user without their consent. In this case, the vulnerability allows an attacker to craft malicious requests that could be executed in the context of an authenticated WooCommerce administrator or user who has sufficient privileges. The vulnerability does not impact confidentiality directly but can lead to integrity issues by allowing unauthorized modification of data or settings within the plugin or connected Google Sheets. The CVSS 3.1 base score is 4.3 (medium severity), reflecting that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), and impacts integrity (I:L) without affecting confidentiality or availability. The scope is unchanged (S:U), meaning the vulnerability affects only the vulnerable component. No known exploits are reported in the wild as of the publication date (July 16, 2025). The vulnerability affects WooCommerce stores using this specific plugin to synchronize or manage data with Google Sheets, potentially allowing attackers to manipulate order data, inventory, or other business-critical information if an authenticated user is tricked into executing the malicious request.

For European organizations using WooCommerce with the GSheetConnector plugin, this vulnerability could lead to unauthorized modification of e-commerce data such as orders, inventory, or customer information managed via Google Sheets integration. While it does not directly expose sensitive data, the integrity compromise could disrupt business operations, cause financial discrepancies, or damage customer trust. Given the widespread adoption of WooCommerce across Europe, especially among small and medium-sized enterprises (SMEs) in countries with strong e-commerce markets like Germany, France, and the UK, the risk is non-trivial. Attackers exploiting this vulnerability could manipulate sales data or inventory records, potentially leading to financial losses or operational disruptions. The requirement for user interaction means phishing or social engineering campaigns could be used to induce administrators to perform malicious actions unknowingly. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits after public disclosure. Organizations relying on this plugin for critical business processes should consider the impact on data integrity and operational continuity.

To mitigate this vulnerability, organizations should first verify if they are using the affected versions of the WooCommerce Google Sheet Connector plugin (up to 1.3.20). Since no patch links are currently available, it is advisable to monitor the vendor's announcements for security updates or patches addressing CVE-2025-54030. In the interim, administrators should implement strict access controls limiting plugin configuration capabilities to trusted users only. Employing web application firewalls (WAFs) with rules to detect and block CSRF attempts can reduce risk. Additionally, enforcing multi-factor authentication (MFA) for WooCommerce admin accounts can help prevent unauthorized access even if a CSRF attack is attempted. Educating users about phishing and social engineering tactics to avoid clicking on suspicious links or performing unintended actions is critical. If feasible, disabling or limiting the plugin's functionality until a patch is available can prevent exploitation. Regularly auditing logs for unusual activity related to the plugin or Google Sheets integration can help detect attempted exploitation early.
