Executive brief
WP Import Export Lite is a WordPress plugin used to import and export website data. The plugin contains a SQL injection vulnerability in its export filter functionality that allows authenticated users—including administrators and other roles with export permissions—to inject malicious SQL queries. This could enable attackers with limited access to extract sensitive data, modify database content, or compromise the entire WordPress installation.
Technical details
The vulnerability is an authenticated SQL injection (SQLi, CWE-89) in the export filter rules processing. The plugin fails to properly sanitize and escape user-supplied filter values before incorporating them into SQL statements. An attacker must hold the export permission (granted by default to administrators, and can be delegated to lower roles) to exploit this vulnerability. Successful exploitation allows execution of arbitrary SQL queries against the WordPress database. The vulnerability was fixed in version 3.9.33; users should update immediately to remediate the issue.
