What the vulnerability does
The Elementor Header & Footer Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via REST API SVG File uploads in all versions up to, and including, 1.6.45 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.
Explanation of Vulnerability in Simple Terms
Ultimate Addons for Elementor versions 1.6.45 and earlier contain a stored cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts that execute in the browsers of other site visitors, including administrators. The vulnerability affects the site's scope, meaning injected code can impact functionality beyond the vulnerable component itself.
What an attacker can do
Inject malicious scripts that run in other users' browsers when they view affected pages.
Potential impact on your site
