At a glance

CVE-2022-0626 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Advanced Admin Search WordPress plugin, affecting versions <= 1.1.2. 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 1.1.6; sites on affected versions should update now. Disclosed May 2022, reported by Ran Crane.

Vulnerability Overview

The Advanced Admin Search WordPress plugin through 1.1.2 does not sanitize and escape some parameters before outputting them back in an admin page, leading to Reflected Cross-Site Scripting.

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 Advanced Admin Search <= 1.1.2 takes a caller who can reach the endpoint. 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 Advanced Admin Search the fix is 1.1.6: builds <= 1.1.2 are affected, anything from 1.1.6 onward is not.

Remediation

Update to version 1.1.6, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Advanced Admin Search: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Advanced Admin Search 1.1.6 closes this, and updating the plugin is the step that ends it.
