Executive Summary

The Quiz and Survey Master (QSM) WordPress plugin before version 11.1.5 has a vulnerability where users with contributor-level access or higher can delete arbitrary output templates without proper authorization. This happens because the plugin fails to check user capabilities before allowing template deletion.

Detection Guidance

Check the installed version of the Quiz and Survey Master plugin. If it is below 11.1.5, the system is vulnerable. Use WordPress admin panel or run a command like 'wp plugin list' in the WordPress directory to verify the version.

Impact Analysis

An attacker with contributor-level access could delete important templates used by quizzes or surveys, potentially disrupting functionality or causing data loss. This could affect the integrity of quizzes or surveys hosted on the WordPress site.

Mitigation Strategies

Update the Quiz and Survey Master plugin to version 11.1.5 or later immediately. Remove unnecessary user roles with contributor-level access or higher if they are not required. Monitor for unauthorized template deletions in logs.
