CVE-2025-3515
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 Drag and Drop Multiple File Upload for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in all versions up to, and including, 1.3.8.9. This makes it possible for unauthenticated attackers to bypass the plugin's blacklist and upload .phar or other dangerous file types on the affected site's server, which may make remote code execution possible on the servers that are configured to handle .phar files as executable PHP scripts, particularly in default Apache+mod_php configurations where the file extension is not strictly validated before being passed to the PHP interpreter.
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 WordPress plugin 'Drag and Drop Multiple File Upload for Contact Form 7' uses blacklist-based file type validation that can be bypassed, allowing unauthenticated attackers to upload .phar files. Since .phar files are treated as executable PHP scripts in default Apache+mod_php configurations, this enables remote code execution.

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 installed versionView plugin details in WordPress admin (Plugins > Installed Plugins > Plugin Details) or read version from plugin's main PHP file header commentAffected if Version is less than 1.3.9.0
-
Verify upload functionality is accessibleNavigate to a Contact Form 7 form that includes the codedropz file upload field and confirm the upload interface loadsAffected if Upload field is present and accessible to unauthenticated or authenticated users
-
Check PHP phar.readonly settingExecute php -i or create a PHP info page to verify the phar.readonly directive valueAffected if phar.readonly is set to 0 or not explicitly set to 1 in php.ini or Apache config
-
Check web server PHP execution handlerIdentify if server runs Apache with mod_php (check phpinfo() for 'Server API' value or server headers)Affected if Server uses mod_php where .phar files can be executed as PHP scripts
