Base vector

AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: Easy Form Builder WordPress plugin versions 1.0 and earlier

Description: The issue concerns the EFBP verify upload file AJAX action, which lacks security measures to verify uploaded files. This allows low-privilege users who are authenticated to upload arbitrary files, potentially leading to remote code execution (RCE).

Recommendations: For Easy Form Builder WordPress plugin versions 1.0 and earlier, consider disabling the EFBP verify upload file AJAX action until a patch is available to prevent the upload of arbitrary files. Restrict access to file upload functionality for low-privilege users to minimize the risk of exploitation.
