CVE-2026-0806 is a SQL Injection vulnerability identified in the WP-ClanWars plugin for WordPress, affecting all versions up to and including 2.0.1. The vulnerability stems from improper neutralization of special elements in the 'orderby' parameter, which is used in SQL queries without sufficient escaping or parameterization. Specifically, the plugin fails to adequately sanitize user-supplied input, allowing an authenticated attacker with administrator-level privileges to append arbitrary SQL commands to existing queries. This can lead to unauthorized extraction of sensitive information from the underlying database. The vulnerability does not affect data integrity or availability, as it is limited to data disclosure. Exploitation does not require user interaction but does require high privileges, which limits the attack vector to trusted users who have administrative access to the WordPress site. The CVSS 3.1 base score is 4.9 (medium severity), with an attack vector of network, low attack complexity, high privileges required, no user interaction, unchanged scope, high confidentiality impact, and no impact on integrity or availability. No public exploits have been reported so far. The vulnerability was published on January 24, 2026, and is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).

For European organizations, the primary impact of CVE-2026-0806 is the potential unauthorized disclosure of sensitive database information, which could include user data, configuration details, or other confidential information stored within the WordPress site’s database. Since exploitation requires administrator-level access, the risk is primarily insider threats or compromised administrator accounts. The vulnerability does not allow modification or deletion of data, nor does it cause denial of service, limiting the impact to confidentiality breaches. However, exposure of sensitive data can lead to further attacks such as credential theft, phishing, or lateral movement within the network. Organizations in Europe that rely on WP-ClanWars for community or gaming-related websites may face reputational damage and regulatory compliance issues, especially under GDPR, if personal data is exposed. The medium severity score reflects a moderate risk that should be addressed promptly to prevent escalation.

1. Immediately restrict administrator-level access to trusted personnel only and enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of compromised credentials. 2. Monitor database query logs for unusual or unexpected SQL commands that could indicate attempted exploitation of the 'orderby' parameter. 3. Apply the vendor’s patch or update the WP-ClanWars plugin to a fixed version as soon as it becomes available. In the absence of an official patch, consider temporarily disabling or removing the plugin if it is not critical to operations. 4. Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'orderby' parameter. 5. Conduct regular security audits and penetration testing focusing on WordPress plugins, especially those with administrative interfaces. 6. Educate administrators about the risks of SQL injection and the importance of safeguarding their credentials. 7. Use principle of least privilege for WordPress roles, ensuring that only necessary users have administrator rights.
