Can you explain this vulnerability to me?
CVE-2025-14635 is a Stored Cross-Site Scripting (XSS) vulnerability in the Happy Addons for Elementor WordPress plugin, affecting all versions up to 3.20.3. It arises because the plugin does not properly sanitize or escape input for the 'ha_page_custom_js' parameter, which allows authenticated users with Contributor-level access or higher to inject arbitrary JavaScript code into pages. This injected code executes whenever any user views the affected page, bypassing the intended restriction that only administrators can add or edit custom JavaScript. [1]
How can this vulnerability impact me? :
This vulnerability can allow attackers with Contributor-level access or above to inject malicious JavaScript into pages on a WordPress site using the Happy Addons plugin. The malicious scripts can execute in the browsers of users who visit the infected pages, potentially leading to theft of user credentials, session hijacking, defacement, or other malicious actions that compromise site security and user data. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
Detection of this vulnerability involves checking if the 'ha_page_custom_js' parameter in the Happy Addons for Elementor plugin is being modified or injected by users with Contributor-level access or above. Since the vulnerability allows stored cross-site scripting via this parameter, you can audit the WordPress database for posts or pages containing suspicious or unexpected JavaScript code in the 'ha_page_custom_js' field. Additionally, monitoring HTTP requests that attempt to modify this parameter by non-administrator users can help detect exploitation attempts. Specific commands are not provided in the resources. [1]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include updating the Happy Addons for Elementor plugin to a version later than 3.20.3, as the vulnerability affects all versions up to and including 3.20.3. Restricting Contributor-level and other non-administrator users from accessing or modifying the 'Custom JS' feature can also help mitigate the risk. Additionally, reviewing and removing any suspicious custom JavaScript code injected via the 'ha_page_custom_js' parameter is recommended. [1, 3]
