CVE-2025-47478 is a high-severity SQL Injection vulnerability (CWE-89) found in Metagauss ProfileGrid, a WordPress plugin used for user profile and community management. The vulnerability affects versions up to 5.9.5.0. SQL Injection occurs due to improper neutralization of special elements in SQL commands, allowing an attacker with at least low-level privileges (PR:L) to inject malicious SQL code remotely (AV:N) without requiring user interaction (UI:N). The vulnerability has a CVSS 3.1 base score of 8.5, indicating a significant risk. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact is primarily on confidentiality (C:H), with potential leakage of sensitive data from the database, while integrity is not impacted (I:N), and availability impact is low (A:L). Exploitation could allow attackers to extract sensitive user data or other confidential information stored in the backend database. Although no known exploits are currently reported in the wild, the vulnerability's nature and ease of exploitation make it a critical concern for organizations using ProfileGrid. The lack of available patches at the time of publication increases the urgency for mitigation.

For European organizations, the impact of this vulnerability could be substantial, especially for those relying on WordPress sites with ProfileGrid for community engagement, membership management, or internal collaboration. Successful exploitation could lead to unauthorized disclosure of personal data, including user profiles, which may contain personally identifiable information (PII). This poses compliance risks under GDPR, potentially resulting in regulatory fines and reputational damage. Additionally, data leakage could facilitate further attacks such as phishing or identity theft. The vulnerability's ability to be exploited remotely without user interaction increases the risk of automated attacks targeting European websites. Organizations in sectors such as education, healthcare, government, and e-commerce, where user data confidentiality is critical, are particularly vulnerable. The limited availability of patches means organizations must act swiftly to implement mitigations to prevent data breaches and maintain trust.

1. Immediate mitigation should include restricting access to the ProfileGrid plugin's administrative and user input interfaces to trusted users only, using IP whitelisting or VPNs where feasible. 2. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting ProfileGrid endpoints. 3. Monitor web server and application logs for unusual or suspicious SQL query patterns indicative of injection attempts. 4. Disable or limit the use of ProfileGrid features that accept user input until a patch is available. 5. Regularly back up databases and ensure backups are stored securely to enable recovery in case of compromise. 6. Engage with Metagauss or the WordPress community to track patch releases and apply updates promptly once available. 7. Conduct code reviews and penetration testing focused on SQL injection vectors within ProfileGrid to identify and remediate any additional weaknesses. 8. Educate administrators and developers about secure coding practices and the risks associated with SQL injection vulnerabilities.
