The issue is fixed in version 1.7.22; sites on affected versions should update now. Disclosed March 2022, reported by p7e4.
Vulnerability Overview
The WordPress WP YouTube Live Plugin is vulnerable to Reflected Cross-Site Scripting via POST data found in the ~/inc/admin.php file which allows unauthenticated attackers to inject arbitrary web scripts in versions up to, and including, 1.7.21.
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 WP YouTube Live <= 1.7.21 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 WP YouTube Live the fix is 1.7.22: builds <= 1.7.21 are affected, anything from 1.7.22 onward is not.
Remediation
Update to version 1.7.22, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to WP YouTube Live: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP YouTube Live 1.7.22 closes this, and updating the plugin is the step that ends it.
