Name of the Vulnerable Software and Affected Versions Groundhogg plugin for WordPress versions up to, and including, 3.7.3.5

Description The issue is related to the lack of file type validation in the gh big file upload() function, which allows authenticated attackers with Author-level access and above to upload arbitrary files on the affected site's server. This may make remote code execution possible.

Recommendations For Groundhogg plugin for WordPress versions up to, and including, 3.7.3.5, update to a version higher than 3.7.3.5 to resolve the issue. As a temporary workaround, consider restricting access to the gh big file upload() function until a patch is available.
