CVE-2025-9318: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in expresstech Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker
The Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to time-based SQL Injection via the ‘is_linking’ parameter in all versions up to, and including, 10.3.1 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 Subscriber-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
The Quiz and Survey Master (QSM) plugin for WordPress suffers from a time-based SQL Injection vulnerability through the 'is_linking' parameter due to improper neutralization of special elements in SQL commands (CWE-89). Authenticated attackers with at least Subscriber privileges can append malicious SQL queries to existing database queries, potentially extracting sensitive data. The vulnerability exists in all plugin versions up to 10.3.1. The CVSS 3.1 base score is 6.5 (medium severity), reflecting network attack vector, low attack complexity, required privileges, no user interaction, unchanged scope, high confidentiality impact, and no integrity or availability impact. No patch or remediation details are currently available.
Potential Impact
Successful exploitation allows an authenticated user with Subscriber-level or higher privileges to perform time-based SQL Injection attacks. This can lead to unauthorized disclosure of sensitive information from the database. The vulnerability does not impact data integrity or availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict plugin access to trusted users and monitor for suspicious activity related to the 'is_linking' parameter. Avoid granting Subscriber-level or higher privileges to untrusted users. Follow vendor updates closely for patch availability.
