## Description

The Event Post plugin for WordPress is vulnerable to Sensitive Information Exposure via child events in all versions up to, and including, 6.1.1, due to published child events copying the title and content of their parent post without checking whether the parent is publicly viewable or password protected. This makes it possible for unauthenticated attackers to read the title and content of private, draft or password-protected posts that have child events through public event lists, when the child events feature is enabled.
