Summary

The Ajax Search Lite WordPress plugin before 4.14.5 does not prevent the deserialization of untrusted input, allowing unauthenticated attackers to perform PHP Object Injection. When a suitable POP chain is present via another installed plugin, this can be leveraged to achieve Remote Code Execution.

Risk Assessment

The risk includes remote code execution by an unauthenticated attacker, potentially leading to full compromise of the WordPress site and data breach.

Recommendation

Update the Ajax Search Lite plugin to version 4.14.5 or later. Also, avoid installing additional plugins that may provide POP chains.
