CVE-2025-49876 is a high-severity SQL Injection vulnerability affecting Metagauss ProfileGrid versions up to 5.9.5.2. The vulnerability arises from improper neutralization of special elements used in SQL commands (CWE-89), allowing an attacker with at least low privileges (PR:L) to inject malicious SQL code remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality (C:H) by potentially exposing sensitive data, with limited impact on availability (A:L) and no impact on integrity (I:N). The scope is changed (S:C), indicating that exploitation could affect resources beyond the initially vulnerable component, possibly impacting the entire database or connected systems. ProfileGrid is a user profile and community management plugin, often used in WordPress environments, which may store and manage user data. Exploiting this vulnerability could allow attackers to extract sensitive information from the backend database, such as user credentials or personal data, posing significant privacy and security risks. Although no known exploits are currently reported in the wild, the high CVSS score (8.5) and the nature of SQL Injection vulnerabilities warrant immediate attention. No official patches or fixes have been linked yet, indicating that organizations must monitor vendor updates closely and consider interim protective measures.

For European organizations, the impact of CVE-2025-49876 can be substantial, especially for those relying on Metagauss ProfileGrid for user management on websites or intranet portals. Successful exploitation could lead to unauthorized disclosure of personal data, violating GDPR requirements and potentially resulting in regulatory fines and reputational damage. The exposure of sensitive user information could also facilitate further attacks such as credential stuffing or identity theft. Given the vulnerability allows remote exploitation without user interaction, attackers could automate attacks at scale, increasing the risk of widespread data breaches. Additionally, the altered scope of the vulnerability suggests that the compromise could extend beyond the immediate application, potentially affecting integrated systems or databases. This is particularly critical for sectors handling sensitive or regulated data, such as finance, healthcare, and government institutions within Europe.

1. Immediate monitoring for vendor updates and patches is essential; apply official fixes as soon as they become available. 2. Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection patterns targeting ProfileGrid endpoints. 3. Conduct thorough code reviews and penetration testing focusing on input validation and sanitization within ProfileGrid configurations. 4. Restrict database user privileges associated with ProfileGrid to the minimum necessary, limiting the potential impact of any injection. 5. Employ parameterized queries or prepared statements if custom development or overrides are used in conjunction with ProfileGrid. 6. Monitor logs for unusual database queries or access patterns indicative of exploitation attempts. 7. Educate administrators and developers about this specific vulnerability to ensure rapid response and awareness. 8. Consider temporary disabling or isolating ProfileGrid functionality if immediate patching is not feasible and the risk is deemed high.
