Ajax Search Lite – Live Search & Filter

The Ajax Search Lite plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 4.13.3 via deserialization of untrusted input. This makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

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.
