At a glance
This record tracks a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Animate It! WordPress plugin, affecting versions < 2.4.0. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). The issue is fixed in version 2.4.0; sites on affected versions should update now. Disclosed March 2022.
Vulnerability Overview
The Animate It! for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘onanimationend’ parameter in versions up to, and including, 2.3.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
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')
Animate It! < 2.4.0 carries this weakness at onanimationend, and reaching it 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 Animate It! the fix is 2.4.0: builds < 2.4.0 are affected, anything from 2.4.0 onward is not.
Remediation
Update to version 2.4.0, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Animate It!: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Animate It! 2.4.0 closes this, and updating the plugin is the step that ends it.
