CVE-2026-16612

FiboSearch < 1.34.1 - Unauthenticated Password-Protected Product Information Disclosure

Published Aug 22, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
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.

Analysis

AI-generated

Technical impact

FiboSearch, a WordPress plugin, has a flaw where password‑protected products are not consistently excluded from two unauthenticated AJAX endpoints. An attacker can trigger the autocomplete search endpoint (dgwt_wcas_ajax_search) or the details panel endpoint (dgwt_wcas_result_details) to obtain names, descriptions, and other metadata of products that are otherwise hidden behind a password. The result is a pure data disclosure with no privilege escalation or code execution.

Affected Systems

The vulnerability affects any WordPress installation running the FiboSearch plugin prior to version 1.34.1. The specific vendor is listed as Unknown:FiboSearch, and the affected product is the plugin itself. No further product versions are identified in the advisory.

Risk and Exploitability

Because the endpoints are reachable without authentication, the attack vector is a simple HTTP request to a publicly accessible AJAX URL. No patch or exploit is currently listed in KEV, and the EPSS score is < 1%, but the ease of the attack suggests that any site with the vulnerable plugin exposed is susceptible to automated enumeration of protected product data. The CVSS score is 5.3, indicating moderate severity.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade FiboSearch to version 1.34.1 or later.
  • If an upgrade is not immediately possible, disable or restrict the dgwt_wcas_ajax_search and dgwt_wcas_result_details endpoints to authenticated users only through plugin configuration or custom code.
  • Review the site’s exposed AJAX endpoints and verify that password‑protected product data is no longer returned to unauthenticated traffic.
