## Description

The WebberZone Top 10 plugin for WordPress is vulnerable to Sensitive Information Exposure via the popular posts output cache in all versions up to, and including, 4.5.3, due to output generated for a visitor who has unlocked a password-protected post being stored in, and served from, a cache shared by all visitors. This makes it possible for unauthenticated attackers to read excerpts of password-protected posts without knowing the password, as long as excerpts and caching are enabled and a visitor who knows the password has loaded the list first.
