CVE-2025-62655 identifies an SQL Injection vulnerability in the MediaWiki Cargo extension maintained by The Wikimedia Foundation, affecting versions 1.39, 1.43, and 1.44. The vulnerability stems from improper neutralization of special elements in SQL commands, classified under CWE-89. This flaw allows an attacker to inject malicious SQL code into database queries executed by the extension. The CVSS 4.0 vector indicates network attack vector (AV:N), high attack complexity (AC:H), requiring privileges (PR:L), and user interaction (UI:P). The vulnerability impacts confidentiality, integrity, and availability at a low level, with limited scope and no scope change (S:N). The vulnerability is not currently known to be exploited in the wild, and no patches have been linked yet. MediaWiki Cargo is a popular extension used to store and query structured data within MediaWiki installations, which are widely deployed in public and private wikis. Exploitation could allow attackers to manipulate or extract data from the underlying database, potentially leading to unauthorized data exposure or modification. However, the requirement for user interaction and limited privileges reduces the likelihood and impact of exploitation. The vulnerability is particularly relevant for organizations hosting MediaWiki instances with the Cargo extension enabled, especially those managing sensitive or critical data.

For European organizations, the impact of CVE-2025-62655 is generally low due to the vulnerability's low severity score and the conditions required for exploitation (user interaction, privileges, and high attack complexity). However, organizations using MediaWiki Cargo extension versions 1.39, 1.43, or 1.44 to manage structured data in wikis could face risks of unauthorized data access or modification if exploited. This could affect data integrity and confidentiality, particularly in environments where MediaWiki is used for knowledge management, documentation, or collaborative projects involving sensitive information. Public sector entities, research institutions, and enterprises relying on MediaWiki for internal or external knowledge bases may be more vulnerable. The lack of known exploits reduces immediate threat levels, but the presence of the vulnerability necessitates proactive mitigation to prevent potential future attacks. Disruption to availability is minimal given the nature of the vulnerability, but data manipulation could indirectly impact operations relying on accurate wiki data.

1. Monitor official Wikimedia Foundation channels for patches addressing CVE-2025-62655 and apply updates promptly once available. 2. Implement strict input validation and sanitization on all user inputs that interact with the Cargo extension to prevent injection of malicious SQL commands. 3. Restrict privileges for users interacting with the MediaWiki Cargo extension to the minimum necessary, reducing the risk posed by compromised or malicious users. 4. Employ web application firewalls (WAFs) with rules designed to detect and block SQL injection attempts targeting MediaWiki installations. 5. Conduct regular security audits and penetration testing focused on MediaWiki extensions to identify and remediate injection flaws. 6. Educate users about the risks of interacting with untrusted content or links that could trigger malicious SQL injection payloads. 7. Consider isolating the database backend or using database-level access controls to limit the impact of potential injection attacks. 8. Review and harden MediaWiki configuration settings to disable or limit features that could be exploited via the Cargo extension.
