CVE-2025-30765 is a Blind SQL Injection vulnerability identified in the WPPOOL FlexStock plugin, which integrates WooCommerce stock management with Google Sheets. The vulnerability stems from improper neutralization of special characters in SQL commands, enabling attackers to inject malicious SQL queries that the backend database executes. Blind SQL Injection means attackers cannot directly see query results but can infer data through response timing or behavior changes. This vulnerability affects all versions up to 3.13.1 inclusive. Exploiting this flaw could allow attackers to extract sensitive information from the database, modify stock data, or disrupt the synchronization process. The plugin’s role in managing inventory data makes this particularly critical for e-commerce operations relying on accurate stock levels. No patches or fixes are currently linked, and no known exploits have been reported in the wild, but the vulnerability is publicly disclosed and could be targeted by attackers. The lack of a CVSS score indicates the need for a severity assessment based on impact and exploitability factors. The vulnerability does not require user interaction but may require the attacker to have some access to the WooCommerce environment or the plugin interface. The plugin’s widespread use in WooCommerce stores globally increases the potential attack surface.

The impact of this Blind SQL Injection vulnerability is significant for organizations using the WPPOOL FlexStock plugin. Attackers exploiting this flaw can gain unauthorized access to sensitive database information, including inventory data, pricing, and potentially customer information if stored in the same database. This can lead to data breaches, loss of data integrity through unauthorized modifications, and disruption of stock synchronization processes, which can affect order fulfillment and customer satisfaction. The compromise of inventory data can also lead to financial losses and reputational damage. Since WooCommerce powers a large number of e-commerce sites worldwide, the scope of affected systems is broad. The vulnerability could be leveraged to pivot to other parts of the network if the database contains additional sensitive information. Although no exploits are currently known in the wild, the public disclosure increases the risk of exploitation attempts. Organizations failing to address this vulnerability may face regulatory compliance issues if customer or business data is exposed.

To mitigate this vulnerability, organizations should first monitor WPPOOL and related security advisories for an official patch or update addressing CVE-2025-30765 and apply it promptly. Until a patch is available, restrict access to the FlexStock plugin interface and WooCommerce admin panel to trusted users only, using strong authentication and IP whitelisting where possible. Implement Web Application Firewalls (WAF) with rules designed to detect and block SQL injection attempts targeting the plugin’s endpoints. Conduct thorough input validation and sanitization on any data inputs related to the plugin, especially those interacting with SQL queries. Regularly audit database logs for unusual query patterns or timing anomalies indicative of Blind SQL Injection exploitation. Consider isolating the database user account used by FlexStock with the least privileges necessary to limit the impact of any injection attempts. Educate development and operations teams about the risks of SQL injection and secure coding practices to prevent similar vulnerabilities in custom integrations. Finally, maintain regular backups of the database to enable recovery in case of data tampering or loss.
