WordPress <= 6.9.1 - Cross-Site Scripting via Client-Side Template Override in Admin Area
WordPress core is vulnerable to Cross-Site Scripting via client-side template overriding in the admin area in all versions up to and including 6.9.1. The wp.template() JavaScript function uses document.getElementById() to locate templates, which matches any HTML element by ID regardless of element type. WordPress admin templates are intended to be <script type="text/html" id="tmpl-*"> elements, but getElementById also matches <div>, <img>, and other injected elements. If an attacker can inject a non-script element with a matching tmpl-* ID, the template content is overridden with attacker-controlled HTML, which is then compiled by Underscore.js _.template() with JavaScript execution support. This is a conditional vulnerability that requires an existing HTML injection vector in the admin context.
