What the vulnerability does
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.
Explanation of Vulnerability in Simple Terms
Ajax Search Lite allows unauthenticated attackers to read sensitive information through a missing authorization check. The plugin does not properly restrict access to certain search functionality, exposing data that should be protected. No user interaction is required; an attacker can exploit this remotely by sending direct requests to the vulnerable endpoint.
What an attacker can do
Read sensitive search data or information that should be restricted to authenticated users.
Potential impact on your site
Sensitive information indexed by the search plugin may be exposed to unauthenticated visitors.
Conditions required to exploit
Network access to the WordPress site; no authentication or user interaction required.
