## Affected

- Unknown FiboSearch: fixed in 1.34.1

## Description

The FiboSearch WordPress plugin before 1.34.1 does not consistently exclude password-protected products from its unauthenticated AJAX endpoints, allowing unauthenticated users to disclose and enumerate password-protected products and their metadata without entering the product password. Two endpoints are affected: the autocomplete search endpoint (dgwt_wcas_ajax_search) and the Details Panel endpoint (dgwt_wcas_result_details) when queried for taxonomy details.
