What the vulnerability does
The Happy Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘_id’ parameter in all versions up to, and including, 3.10.8 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
Happy Addons for Elementor versions up to 3.10.8 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 the 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
Authenticated users can inject code affecting other visitors; admin accounts are at risk if they view compromised content.
Conditions required to exploit
Attacker must have a low-privilege user account on the site (e.g., subscriber or contributor role).
