CVE-2025-62655 identifies a SQL Injection vulnerability in the MediaWiki Cargo extension versions 1.39, 1.43, and 1.44. The vulnerability stems from improper neutralization of special characters in SQL commands, classified under CWE-89. This flaw allows an attacker to inject malicious SQL code, potentially manipulating the database queries executed by the extension. The attack vector is network-based and requires partial authentication with user interaction, making exploitation more complex. The CVSS 4.0 vector indicates a low base score of 2.1, reflecting high attack complexity, partial privileges, and limited impact on confidentiality, integrity, and availability. The vulnerability does not affect system confidentiality or availability severely but can lead to unauthorized data access or modification within the scope of the extension's database. No public exploits or patches are currently documented, but the Wikimedia Foundation is aware and has published the vulnerability. The Cargo extension is widely used in MediaWiki deployments for structured data storage and querying, making the vulnerability relevant for organizations relying on this extension for content management. Attackers exploiting this flaw could execute arbitrary SQL commands, potentially leading to data leakage or corruption, but the requirement for user interaction and authentication reduces the risk of widespread exploitation.

For European organizations, the impact of CVE-2025-62655 is primarily related to data confidentiality and integrity within MediaWiki Cargo extension databases. Organizations using affected versions may experience unauthorized data access or manipulation if an attacker successfully exploits the vulnerability. This could compromise sensitive information stored in MediaWiki instances, especially in governmental, educational, or research institutions that rely on MediaWiki for collaborative knowledge management. The limited severity and exploitation complexity reduce the likelihood of large-scale attacks, but targeted attacks against high-value data repositories remain a concern. Additionally, exploitation could undermine trust in publicly accessible wikis or internal knowledge bases, impacting operational continuity and reputational standing. Since no known exploits are in the wild, the immediate risk is low, but the potential for future exploitation exists if patches are not applied promptly.

1. Monitor official Wikimedia Foundation channels for patches addressing CVE-2025-62655 and apply updates to the MediaWiki Cargo extension as soon as they become available. 2. Implement strict input validation and sanitization on all user inputs interacting with the Cargo extension to prevent injection of malicious SQL code. 3. Restrict access to the Cargo extension interfaces and administrative functions to trusted users only, minimizing the attack surface. 4. Employ web application firewalls (WAFs) with rules tailored to detect and block SQL injection attempts targeting MediaWiki extensions. 5. Conduct regular security audits and penetration testing focused on MediaWiki deployments to identify and remediate injection vulnerabilities proactively. 6. Educate users and administrators about the risks of SQL injection and the importance of cautious interaction with wiki content that may trigger database queries. 7. Consider isolating the MediaWiki database or using database-level permissions to limit the impact of any potential injection attacks.
