Name of the Vulnerable Software and Affected Versions Multi Step Form plugin for WordPress versions up to, and including, 1.7.23

Description The issue is related to a missing capability check on the fw upload file AJAX action, which allows unauthenticated attackers to upload limited file types, such as images. This makes it possible for attackers to upload files without proper authorization.

Recommendations For versions up to, and including, 1.7.23, update to a version that includes a fix for the missing capability check on the fw upload file AJAX action. As a temporary workaround, consider disabling the fw upload file AJAX action until a patch is available. Restrict access to the fw upload file AJAX endpoint to minimize the risk of exploitation.
