CVE-2025-62015 identifies a SQL Injection vulnerability in the Advanced Coupons for WooCommerce Coupons plugin developed by Josh Kohlbach, affecting versions up to and including 4.6.8. The vulnerability arises from improper neutralization of special elements in SQL commands, allowing an attacker with authenticated high-level privileges to inject malicious SQL code into the backend database queries. This can lead to unauthorized disclosure of sensitive data (confidentiality impact), and partial modification of data (integrity impact), though availability remains unaffected. The CVSS v3.1 score of 7.6 reflects a high severity due to network attack vector, low attack complexity, required privileges, no user interaction, and a scope change indicating the vulnerability affects resources beyond the initially vulnerable component. The plugin is widely used in WooCommerce-based e-commerce platforms to manage coupons and discounts, making it a valuable target for attackers seeking to manipulate sales data or extract customer information. No public exploits have been reported yet, but the vulnerability’s characteristics suggest it could be weaponized by attackers with access to authenticated accounts, such as compromised admin credentials or insider threats. The lack of official patches or mitigation guidance in the provided data emphasizes the urgency for vendors and users to monitor updates and apply fixes promptly once available.

For European organizations operating WooCommerce e-commerce platforms with the Advanced Coupons plugin, this vulnerability poses a significant risk to customer data confidentiality and the integrity of promotional and transactional data. Attackers exploiting this flaw could extract sensitive customer information, including personal and payment-related data, leading to privacy violations and regulatory non-compliance under GDPR. Manipulation of coupon data could also result in financial losses through unauthorized discounts or fraudulent transactions. The integrity compromise may undermine trust in the e-commerce platform and damage brand reputation. Since availability is not impacted, the threat primarily concerns data breaches and fraud rather than service disruption. Given the prevalence of WooCommerce in European markets, especially in countries with strong e-commerce sectors, the potential scale of impact is substantial. Organizations failing to address this vulnerability risk regulatory penalties, customer attrition, and financial damage.

Organizations should immediately verify if they are using Advanced Coupons for WooCommerce Coupons plugin version 4.6.8 or earlier and plan to upgrade to a patched version once released by the vendor. Until a patch is available, restrict plugin access to only trusted administrators and monitor for unusual database queries or coupon modifications. Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the plugin’s endpoints. Conduct regular audits of user privileges to minimize the number of accounts with high-level access. Employ database activity monitoring to detect anomalous SQL commands indicative of injection attempts. Additionally, ensure comprehensive logging and alerting are enabled for coupon management activities. Educate administrators on the risks of credential compromise and enforce strong authentication mechanisms, such as multi-factor authentication (MFA), to reduce the risk of unauthorized access. Finally, maintain up-to-date backups of the database to enable recovery in case of data manipulation.
