CVE-2025-49033 is a high-severity SQL Injection vulnerability affecting Metagauss ProfileGrid versions up to 5.9.5.3. The vulnerability arises from improper neutralization of special elements in SQL commands, classified under CWE-89. Specifically, the flaw allows an attacker with at least low-level privileges (PR:L) to perform Blind SQL Injection attacks remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality severely (C:H), as attackers can extract sensitive data from the backend database, but does not affect integrity (I:N) and only causes limited availability impact (A:L). The scope is changed (S:C), indicating that exploitation can affect resources beyond the vulnerable component, potentially impacting the entire system or other connected components. Blind SQL Injection means attackers cannot directly see query results but can infer data by observing application behavior or timing, making exploitation more complex but still feasible. No public exploits are currently known in the wild, and no patches have been linked yet, indicating that organizations using ProfileGrid should prioritize monitoring and mitigation. ProfileGrid is a WordPress plugin used for user profile and community management, often deployed in websites requiring user registration and interaction features. The vulnerability could allow attackers to extract user data, including credentials or personal information, leading to privacy breaches and compliance violations.

For European organizations, the impact of this vulnerability is significant due to the potential exposure of sensitive personal data protected under GDPR. Many European companies and institutions use WordPress-based platforms with plugins like ProfileGrid for community engagement, membership sites, or internal collaboration portals. Exploitation could lead to unauthorized data disclosure, undermining trust and causing regulatory penalties. The confidentiality breach could expose user identities, contact details, or other private information. Although integrity and availability impacts are limited, the loss of confidentiality alone is critical in sectors such as healthcare, education, finance, and government services prevalent in Europe. Additionally, the scope change means that attackers might leverage this vulnerability to pivot within the network or access other connected systems, increasing the overall risk. The lack of known exploits in the wild provides a window for proactive defense, but the high CVSS score and ease of remote exploitation with low privileges necessitate urgent attention.

European organizations should implement the following specific mitigations: 1) Immediately audit all WordPress sites for the presence of the ProfileGrid plugin and identify versions up to 5.9.5.3. 2) Apply patches or updates from Metagauss as soon as they become available; if no official patch exists, consider temporarily disabling the plugin or restricting its access to trusted users only. 3) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting ProfileGrid endpoints, focusing on blind SQL injection attack signatures. 4) Conduct thorough input validation and sanitization on all user-supplied data interacting with ProfileGrid, especially parameters involved in SQL queries. 5) Restrict database user privileges associated with the plugin to the minimum necessary, preventing unauthorized data access beyond what is required. 6) Monitor logs for unusual query patterns or repeated failed attempts that may indicate exploitation attempts. 7) Educate administrators and developers about the risks of SQL injection and the importance of secure coding practices. 8) Consider network segmentation to isolate critical systems from web-facing servers hosting vulnerable plugins. These targeted actions go beyond generic advice by focusing on the plugin-specific context and operational environment.
