CVE-2025-23967 is a critical SQL Injection vulnerability identified in the wpopal GG Bought Together plugin for WooCommerce, affecting versions up to 1.0.2. The vulnerability stems from improper neutralization of special elements used in SQL commands (CWE-89), allowing an unauthenticated remote attacker to inject malicious SQL queries directly into the backend database. The CVSS 3.1 score of 9.3 reflects the high severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component. The impact is primarily on confidentiality (C:H), with no direct integrity (I:N) or availability (A:L) impact noted, although availability impact is low but present. This vulnerability allows attackers to extract sensitive data from the database, such as customer information, order details, or payment data, which can lead to data breaches, privacy violations, and potential regulatory non-compliance. Since the plugin is used within WooCommerce, a widely adopted e-commerce platform on WordPress, the vulnerability poses a significant risk to online stores using this plugin. No patches or fixes are currently available, and no known exploits have been observed in the wild yet, but the ease of exploitation and critical impact make it a high priority for remediation once patches are released.

For European organizations, particularly e-commerce businesses using WooCommerce with the GG Bought Together plugin, this vulnerability presents a substantial risk. Exploitation could lead to unauthorized disclosure of personal data protected under GDPR, resulting in legal penalties and reputational damage. The breach of customer data could undermine consumer trust and cause financial losses due to fraud or identity theft. Additionally, attackers could leverage extracted data for further attacks or fraud schemes. The critical nature of the vulnerability and its ability to be exploited remotely without authentication means that European online retailers must urgently assess their exposure. The potential for cross-border data leakage also raises concerns for multinational companies operating in multiple European countries. Given the e-commerce sector's importance in Europe, this vulnerability could disrupt business operations and customer confidence if exploited.

Immediate mitigation steps include: 1) Temporarily disabling the GG Bought Together plugin until a security patch is released to eliminate the attack surface. 2) Monitoring web application logs and database access patterns for suspicious queries indicative of SQL injection attempts. 3) Employing Web Application Firewalls (WAFs) configured with rules to detect and block SQL injection payloads targeting WooCommerce plugins. 4) Ensuring that all WooCommerce and WordPress installations are updated to the latest versions, and subscribing to vendor security advisories for prompt patch deployment. 5) Implementing least privilege principles on database accounts used by WooCommerce to limit data exposure if compromised. 6) Conducting security audits and penetration testing focused on SQL injection vectors in custom or third-party plugins. 7) Educating development and IT teams about secure coding practices to prevent similar vulnerabilities in custom extensions. These measures go beyond generic advice by focusing on immediate plugin disablement, active monitoring, and access control hardening specific to the affected environment.
