CVE-2025-3280 is a SQL Injection vulnerability identified in the ELEX WooCommerce Advanced Bulk Edit Products, Prices & Attributes plugin for WordPress, affecting all versions up to and including 1.4.9. The vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89), specifically through the 'attribute_value_filter' parameter. This parameter is insufficiently escaped and the existing SQL queries are not properly prepared, allowing an attacker to inject arbitrary SQL code. Notably, exploitation requires the attacker to be authenticated with at least Subscriber-level access, which is a relatively low privilege level in WordPress. By appending additional SQL queries, an attacker can extract sensitive information from the database, potentially including customer data, product details, pricing, and other confidential business information. Although no known exploits are currently in the wild, the vulnerability presents a significant risk due to the widespread use of WooCommerce and the plugin in question. The lack of a patch at the time of reporting further increases the urgency for mitigation. The vulnerability affects the confidentiality and integrity of data stored in the backend database, with potential indirect impacts on availability if the injection is leveraged to disrupt database operations. The attack vector is web-based and requires user interaction limited to authenticated access, making it feasible for insider threats or compromised low-privilege accounts to exploit the flaw.

For European organizations, the impact of this vulnerability can be substantial, especially for e-commerce businesses relying on WooCommerce and the ELEX plugin to manage product catalogs and pricing. Successful exploitation could lead to unauthorized disclosure of sensitive customer information, including personal data protected under GDPR, resulting in regulatory penalties and reputational damage. Additionally, manipulation or extraction of pricing and inventory data could disrupt business operations and competitive positioning. The vulnerability also poses risks to data integrity, potentially allowing attackers to alter product information or pricing, which could lead to financial losses or customer trust erosion. Given the requirement for authenticated access, insider threats or compromised user accounts pose a realistic risk vector. The absence of known exploits currently reduces immediate threat levels but does not eliminate the risk, especially as attackers often develop exploits rapidly after public disclosure. The medium severity rating reflects the balance between the required authentication and the potential for significant data compromise. Organizations with large WooCommerce deployments or those in highly regulated sectors such as finance, retail, or healthcare are particularly at risk.

1. Immediate mitigation should include restricting Subscriber-level user capabilities to the minimum necessary, reviewing and tightening user role permissions to reduce the risk of low-privilege account exploitation. 2. Implement Web Application Firewall (WAF) rules specifically targeting SQL injection patterns on the 'attribute_value_filter' parameter to block malicious payloads. 3. Monitor logs for unusual database query patterns or repeated failed attempts to manipulate the 'attribute_value_filter' parameter. 4. Conduct a thorough audit of all user accounts with Subscriber-level or higher access to identify and remediate compromised or unnecessary accounts. 5. Until an official patch is released, consider disabling or removing the ELEX WooCommerce Advanced Bulk Edit Products, Prices & Attributes plugin if feasible, or restrict its usage to trusted administrators only. 6. Employ database activity monitoring tools to detect anomalous queries indicative of injection attempts. 7. Educate site administrators and users about the risks of phishing or credential compromise that could lead to exploitation. 8. Upon availability, promptly apply vendor patches or updates addressing this vulnerability. 9. For custom or in-house developed plugins or extensions, review and refactor SQL query construction to use parameterized queries or prepared statements to prevent injection vulnerabilities.
