At a glance

CVE-2026-122664 is a medium-severity Improper Neutralization of Input During Web Page Generation vulnerability in the Broadcast Live Video WordPress plugin, affecting versions <= 7.3.14. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication.

Vulnerability Overview

The Broadcast Live Video – Live Streaming : WebRTC, HLS, RTSP, RTMP plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in all versions up to, and including, 7.3.14. This is due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

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

Reaching this weakness in Broadcast Live Video <= 7.3.14 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 Broadcast Live Video the fix is 7.3.15: builds <= 7.3.14 are affected, anything from 7.3.15 onward is not.

Remediation

Update to version 7.3.15, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Broadcast Live Video: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Broadcast Live Video 7.3.15 closes this, and updating the plugin is the step that ends it.
