Vulnerability Overview

The Slide Anything WordPress plugin before 2.3.44 does not sanitize and escape sliders' description, which could allow high privilege users such as editor and above to perform Cross-Site Scripting attacks even when the unfiltered_html 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 interaction from a victim user.

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

Reaching this weakness in Slide Anything < 2.3.44 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 Slide Anything the fix is 2.3.44: builds < 2.3.44 are affected, anything from 2.3.44 onward is not.

Remediation

Update to version 2.3.44, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Slide Anything: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Slide Anything 2.3.44 closes this, and updating the plugin is the step that ends it.
