WordPress · Forminator · CVE-2023-4596
**Name of the Vulnerable Software and Affected Versions**
Forminator plugin for WordPress versions up to, and including, 1.24.6
**Description**
The Forminator plugin for WordPress is vulnerable to arbitrary file uploads due to file type validation occurring after a file has been uploaded to the server in the `upload post image()` function. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server, which may make remote code execution possible. The vulnerability affects over 400,000 sites.
**Recommendations**
For Forminator plugin for WordPress versions up to, and including, 1.24.6:
Update to a version later than 1.24.6 to resolve the issue.
As a temporary workaround, consider disabling the `upload post image()` function until a patch is available.
Restrict access to the upload functionality to minimize the risk of exploitation.
