CVE-2025-0394
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe WordPress CRM, Email & Marketing Automation for WordPress | Award Winner — Groundhogg plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the gh_big_file_upload() function in all versions up to, and including, 3.7.3.5. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Groundhogg plugin is installedNavigate to WordPress admin > Plugins, look for 'Groundhogg' in the list of installed plugins.
