What the vulnerability does
01Description
The Elementor Header & Footer Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the url attribute within the plugin's Site Title widget in all versions up to, and including, 1.6.35 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
02Summary
Ultimate Addons for Elementor versions up to 1.6.35 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 scope, meaning injected code can interact with other site functionality. Update to a version newer than 1.6.35 to remediate.
