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.
-
Confirm in5 Embed plugin is installedCheck the WordPress plugins directory (wp-content/plugins/) for a folder named 'in5-embed' or similar. In WordPress admin, navigate to Plugins > Installed Plugins and look for 'in5 Embed' or 'in5 Embed WordPress plugin'.Affected if The plugin folder exists in wp-content/plugins/ regardless of active status
-
Identify installed versionIn WordPress admin, go to Plugins > Installed Plugins and find in5 Embed. The version number is displayed below the plugin name. Alternatively, check the plugin's main PHP file header or readme.txt for the 'Version' field.Affected if Version is 3.1.5 or lower (any version up to and including 3.1.5)
-
Verify plugin is activeIn WordPress admin, go to Plugins > Installed Plugins. Check if in5 Embed shows as 'Active' under the plugin status. Alternatively, check the wp_options table for an option named 'active_plugins' and see if the plugin is listed.Affected if Plugin is activated on the WordPress site
-
Check for unauthorized uploaded filesExamine the WordPress uploads directory (wp-content/uploads/) and any custom upload paths configured for the plugin. Look for unexpected file extensions such as .php, .phtml, .php5, .phar, or other executable files that were not intentionally uploaded by administrators.Affected if Unexpected PHP files or other executable scripts appear in upload directories
-
Review server access logs for upload endpoint probesSearch web server access logs (Apache, Nginx, or similar) for POST requests to the plugin's upload handler. Look for patterns like uploads, file-upload, or similar endpoints that may indicate exploitation attempts. Also check for requests with suspicious file extensions in the request body.Affected if Log entries show unauthenticated POST requests to plugin upload functionality with executable file extensions
You are affected if in5 Embed plugin version 3.1.5 or lower is installed and active on your WordPress site, as this enables unauthenticated attackers to upload executable files.
