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.
-
Verify epiphyt Form Block plugin is installedNavigate to WordPress admin dashboard, go to Plugins > Installed Plugins, and search for 'Form Block' by epiphyt or check the plugins directory for the Form Block plugin filesAffected if The plugin is found installed on the WordPress site

Identify the installed version of Form BlockIn the WordPress plugins list, click on the Form Block plugin to view its details, or inspect the plugin's main PHP file header for the 'Version' fieldAffected if The version number is lower than the patched version (compare against latest release)
-
Check if any forms have file upload fields enabledNavigate to the form builder or form settings within the plugin, and inspect each form configuration for upload/file input field typesAffected if One or more forms contain enabled file upload input fields
-
Inspect upload directories for suspicious script filesLocate the upload directory (typically wp-content/uploads or wp-content/uploads/form-block), and list all files with extensions such as .php, .phtml, .php5, .php7, .phar, or .phptAffected if Any PHP or other script executable files are present in upload directories (potential web shells)

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.
From vendor dataImmediately update to the latest version of Form Block. Until patched, disable form file upload functionality and implement web server-level controls to prevent script execution in upload directories.
