At a glance

CVE-2022-1469 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the FiboSearch WordPress plugin, affecting versions < 1.17.0. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.17.0; sites on affected versions should update now. Disclosed May 2022, reported by Dipak Panchal (th3.d1p4k).

Vulnerability Overview

The FiboSearch WordPress plugin before 1.17.0 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks when the unfiltered_html capability is disallowed.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in FiboSearch < 1.17.0 takes an account at Admin level or above. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For FiboSearch the fix is 1.17.0: builds < 1.17.0 are affected, anything from 1.17.0 onward is not.

Remediation

Update to version 1.17.0, or a newer patched version

How does WordSec protect against this?

An attacker needs Admin access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: FiboSearch 1.17.0 closes this, and updating the plugin is the step that ends it.
