This vulnerability involves missing authorization checks in the Opinion Stage Poll, Survey & Quiz Maker Plugin (versions up to 19.12.0), which leads to incorrectly configured access control security levels. The flaw could allow unauthorized users to perform actions that should require authorization, impacting the availability of the affected system. The CVSS score of 5.3 reflects a medium severity with network attack vector, low attack complexity, no privileges required, no user interaction, and unchanged confidentiality and integrity but reduced availability. There is no vendor advisory or patch information available, and no known exploits have been reported.

The vulnerability impacts availability by allowing unauthorized actions due to missing authorization controls. Confidentiality and integrity are not affected. No known exploitation in the wild has been reported. The medium severity rating and CVSS score of 5.3 indicate a moderate risk that could affect system availability if exploited.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor the vendor's communications for updates. Until a fix is available, restrict access to the plugin's administrative interfaces and review access control configurations to minimize exposure.
