## Description

The Advanced Woo Search plugin for WordPress is vulnerable to Sensitive Information Exposure via the search results cache in all versions up to, and including, 3.73. Logged-in users with no role on the site shared one cache entry with logged-out visitors. This makes it possible for unauthenticated attackers to read search results cached for such a user, including products that another plugin hides from logged-out visitors, when search caching is on and such a user has searched the same term.
