Description

The Poll Maker – Versus Polls, Anonymous Polls, Image Polls plugin for WordPress is vulnerable to a Race Condition in all versions up to, and including, 5.7.7. This is due to the plugin not properly restricting a user's ability to fill out a poll multiple times.. This makes it possible for unauthenticated attackers to fill out a poll multiple times.
