CVE-2024-56293

Vulnerability

The vulnerability resides in the Advanced Form Integration plugin for WordPress, where improper neutralization of user input during web page generation leads to Stored Cross-Site Scripting (XSS). Affected versions are from n/a through 1.95.0. The plugin allows users to store data that is later displayed on admin pages without proper sanitization, enabling the injection of arbitrary JavaScript code[1].

Exploitation

An attacker needs to have the ability to input data via forms or integrations that the plugin processes, such as form submissions or other user-supplied content. The attacker crafts a payload containing JavaScript code that bypasses output encoding. When an administrator views the stored data in the WordPress admin area, the script executes in the context of the admin's session[1].

Impact

Successful exploitation leads to stored XSS, allowing the attacker to execute arbitrary JavaScript in the browser of an authenticated admin user. This can result in session hijacking, defacement, or theft of sensitive information. The attack requires no privileges higher than being able to submit a form or trigger an integration, but the impact is escalated to the admin level through the XSS[1].

Mitigation

The vendor has not yet released a patched version for this vulnerability. As of the publication date, versions through 1.95.0 remain affected. Users should monitor the plugin repository for updates and apply the fixed version as soon as it becomes available. No workaround is documented in the available references[1].
