Description
The Ajax Search Lite plugin for WordPress is vulnerable to Basic Information Exposure due to missing authorization in its AJAX search handler in all versions up to, and including, 4.13.1. This makes it possible for unauthenticated attackers to issue repeated AJAX requests to leak the content of any protected post in rolling 100‑character windows.
