Can you explain this vulnerability to me?
The Flipbox Addon for Elementor plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its Flipbox widget's button URL custom_attributes field. This vulnerability exists in all versions up to and including 2.1.1 because the plugin does not properly validate custom attribute names.
Specifically, the plugin uses the esc_html() function on attribute names, which does not prevent event handler attributes like onmouseover or onclick from being used. This allows authenticated users with author-level access or higher to inject malicious scripts that will execute whenever any user views the affected page.
How can this vulnerability impact me? :
This vulnerability can allow attackers with author-level access or higher to inject arbitrary scripts into web pages. These scripts will execute in the browsers of users who visit the infected pages.
- It can lead to theft of user data such as cookies or session tokens.
- It can enable attackers to perform actions on behalf of users without their consent.
- It may result in defacement or manipulation of website content.
- It can damage the trust and reputation of the website.
