CVE-2025-6739: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in bauc WPQuiz
The WPQuiz plugin for WordPress is vulnerable to SQL Injection via the 'id' attribute of the 'wpquiz' shortcode in all versions up to, and including, 0.4.2 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 Contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
AI Analysis
Technical Summary
CVE-2025-6739 is an SQL Injection vulnerability in the WPQuiz plugin for WordPress affecting all versions up to 0.4.2. The issue is due to improper neutralization of special elements in the 'id' attribute of the 'wpquiz' shortcode, allowing authenticated users with Contributor-level privileges or higher to inject additional SQL queries. This occurs because user input is not sufficiently escaped and the SQL queries lack proper preparation, enabling attackers to extract sensitive data from the database. The vulnerability has a CVSS 3.1 base score of 6.5 (medium severity), with network attack vector, low attack complexity, and requiring privileges.
Potential Impact
Successful exploitation allows authenticated users with Contributor-level access or above to perform SQL Injection attacks, potentially extracting sensitive information from the database. The vulnerability does not impact integrity or availability but compromises confidentiality. No known active exploits have been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Contributor-level access to trusted users only and consider disabling the WPQuiz plugin if possible. Monitor for vendor updates regarding patches or official mitigations.
