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 if Themify Builder plugin is installedCheck the WordPress plugins directory (wp-content/plugins/) for the themify-builder folder, or view the installed plugins list in WordPress admin under Plugins > Installed PluginsAffected if Themify Builder plugin is present in the WordPress installation
-
Determine installed Themify Builder versionOpen the main plugin file (typically themify-builder/themify-builder.php) and locate the 'Version' header in the plugin comments, or use WP-CLI command: wp plugin list --fields=name,version --filter=themify-builderAffected if Version cannot be determined or is 7.7.4 or lower
-
Compare version against affected rangeCompare the installed version number to the affected range: any version through 7.7.4 (including all versions below 7.7.4)Affected if Installed version is 7.7.4 or any earlier version such as 7.7.3, 7.6.0, etc.
-
Check for reflected user input in Builder URLsReview access logs or use a browser to inspect URLs containing Builder-related paths (such as /?themify=... or any admin ajax endpoints used by the plugin). Look for unsanitized query parameters that might be reflected in the page response without encodingAffected if URL parameters are reflected in HTML output without proper encoding (visible in page source as raw unescaped input)
-
Audit recent access logs for XSS exploitation attemptsSearch web server access logs (Apache/nginx) for requests to Themify Builder endpoints containing suspicious patterns like <script>, javascript:, onerror=, or other HTML/script tags in query parametersAffected if Logs contain requests with script injection patterns targeting Themify Builder URLs
The environment is affected if Themify Builder plugin is installed and the installed version is 7.7.4 or lower, as all such versions contain the reflected XSS vulnerability in unsanitized user input handling.

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 dataUpgrade to the latest version of Themify Builder when available, or apply input validation and proper output escaping (esc_html, esc_attr, etc.) to all user-supplied data before rendering in HTML context.
