CVE-2025-12352
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 Gravity Forms plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the copy_post_image() function in all versions up to, and including, 2.9.20. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. This only impacts sites that have allow_url_fopen set to `On`, the post creation form enabled along with a file upload field for the post
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Gravity Forms WordPress plugin is vulnerable to arbitrary file uploads due to missing file type validation in the copy_post_image() function. Unauthenticated attackers can upload malicious files leading to potential remote code execution, but exploitation requires three conditions: allow_url_fopen enabled, post creation form enabled, and a file upload field present in that form.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Gravity Forms versionIn WordPress admin, go to Forms > About, or check the plugins list in WP-Admin > Plugins. Compare the installed version to 2.9.21.Affected if The installed version is below 2.9.21 and the plugin is active.
-
Verify PHP allow_url_fopen settingCheck php.ini for 'allow_url_fopen = On' or run 'php -i | grep allow_url_fopen' from command line. Alternatively, use a PHP info page or plugin to view PHP settings.Affected if allow_url_fopen is enabled (set to On or 1).
-
Confirm post creation form feature is activeIn WordPress admin, go to Forms > Settings > Post Creation. Check if any forms have post creation enabled.Affected if At least one form has the post creation feature turned on.
-
Identify file upload fields in post creation formsIn WordPress admin, edit each form with post creation enabled. Look for any File Upload field type added to the form.Affected if A file upload field exists in a form that also has post creation enabled.
You are affected if Gravity Forms is below version 2.9.21 AND allow_url_fopen is enabled AND you have a form with both post creation and a file upload field enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate to Gravity Forms version 2.9.21 or later when available. Until then, disable allow_url_fopen in php.ini, or disable the post creation form feature with file upload fields as a temporary workaround.
Gravity Forms 2.9.21 or latest available version
- 1. Navigate to the WordPress admin dashboard
- 2. Go to Plugins > Installed Plugins
