CVE-2026-0806 in WP-ClanWars Plugin
Summary
by MITRE • 01/24/2026
The WP-ClanWars plugin for WordPress is vulnerable to SQL Injection via the 'orderby' parameter in all versions up to, and including, 2.0.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The WP-ClanWars plugin for WordPress represents a significant security vulnerability classified as CVE-2026-0806, which exposes systems to sophisticated SQL injection attacks. This vulnerability affects all versions up to and including 2.0.1, making it a widespread concern for WordPress administrators who have deployed this particular plugin. The flaw resides in the plugin's handling of the 'orderby' parameter, which serves as a critical entry point for malicious exploitation. The vulnerability stems from inadequate input sanitization and insufficient parameter preparation within the SQL query construction process, creating a pathway for attackers to manipulate database operations through seemingly benign user input.
The technical implementation of this vulnerability demonstrates a classic case of improper input validation and query construction practices that align with CWE-89, which specifically addresses SQL injection flaws. Attackers with administrator-level access or higher can exploit this weakness by manipulating the 'orderby' parameter to inject malicious SQL code into existing database queries. The vulnerability's design flaw allows for the concatenation of additional SQL statements to pre-existing queries without proper sanitization, effectively bypassing standard security controls. This particular weakness operates at the database layer, where user-supplied parameters are directly incorporated into SQL statements without adequate escaping or parameterization mechanisms.
The operational impact of this vulnerability extends beyond simple data extraction, as it provides attackers with the capability to perform comprehensive database reconnaissance and potentially escalate their privileges within the affected WordPress environment. Authenticated attackers can leverage this vulnerability to extract sensitive information including user credentials, administrative details, and potentially other database contents that may contain confidential data. The attack vector requires only administrative access, which makes this vulnerability particularly dangerous as it can be exploited by insiders or compromised administrator accounts. This scenario creates a high-risk environment where the attacker's capabilities are limited only by their understanding of the database schema and the plugin's functionality.
Mitigation strategies for CVE-2026-0806 should prioritize immediate plugin updates to versions that address the SQL injection vulnerability, as recommended by the plugin developers and security vendors. Organizations should implement comprehensive input validation and parameterized queries throughout their WordPress installations to prevent similar vulnerabilities from manifesting in other components. Network segmentation and access control measures should be enforced to limit the potential damage from compromised administrator accounts, while regular security audits and penetration testing can help identify other potential entry points. The vulnerability's classification under ATT&CK technique T1078 highlights the importance of privileged access management and monitoring for suspicious administrative activities. Additionally, implementing web application firewalls and database activity monitoring solutions can provide additional layers of defense against exploitation attempts targeting this specific vulnerability pattern.
