ExpressTech Systems Quiz And Survey Master vulnerabilities such as missing authorization allow attackers to bypass intended security boundaries. By exploiting incorrectly configured access control security levels, an attacker can gain unauthorized access to protected areas of the plugin, potentially exposing sensitive data or administrative functions. This weakness directly maps to CWE-862 and results in the ability to read, modify, or delete quiz and survey content without permission.

Affected systems include WordPress sites installing ExpressTech Systems Quiz And Survey Master (quiz-master-next) version 10.3.2 or earlier. The vulnerability applies to all releases prior to 10.3.3, regardless of the specific minor revision. Administrators should check the plugin version on each WordPress installation to confirm susceptibility.

Risk assessment shows a CVSS score of 5.3, indicating a moderate impact. The EPSS score is below 1%, suggesting a low likelihood of exploitation at present, and it is not listed in the CISA KEV catalog. The attack vector likely requires an existing authenticated user or session to target administrative endpoints, though the description indicates incorrectly configured limits that could be abused without credentials. Given the moderate score and low exploitation probability, the primary concern is preventing potential unauthorized content access rather than catastrophic damage.
