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 Hustle plugin installationLog into WordPress admin dashboard and navigate to Plugins > Installed Plugins. Look for 'Hustle' or 'Hustle - Email Marketing, Lead Generation, Optins, Popups' in the list of active plugins.Affected if Hustle plugin appears in the WordPress site plugins list
-
Determine installed Hustle versionIn WordPress admin, go to Plugins > Installed Plugins. Click on the Hustle plugin to view its details, or check the plugin file headers via FTP/SSH at wp-content/plugins/hustle/inchustle.php for the 'Version' comment field, or use WP-CLI: wp plugin list --filter=name=hustle --format=tableAffected if Version displayed is 7.8.10.1 or earlier (any version 'through' 7.8.10.1 according to the CVE)
-
Compare version to affected rangeThe affected versions are 'through 7.8.10.1'. If your installed version is 7.8.10.1 or lower (e.g., 7.8.10, 7.8.9, etc.), your installation falls within the vulnerable range. Versions 7.8.10.2 and later are patched.Affected if Installed version is 7.8.10.1 or any earlier version in the 7.x line
-
Check for unauthorized access indicatorsReview WordPress access logs and Hustle-specific activity logs for requests to plugin endpoints (such as ajax/admin-ajax.php calls or hustle-related REST API routes) originating from unauthenticated users or users lacking administrator-level permissions.Affected if Log entries show unauthenticated or low-privilege users successfully accessing Hustle functionality that should require admin permissions
Your environment is affected if the Hustle plugin is installed with version 7.8.10.1 or any earlier version, since the missing authorization flaw allows unauthorized access regardless of specific configuration.

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 dataApply the vendor patch/upgrade to Hustle version 7.8.10.2 or later. If immediate patching is not possible, review and restrict access to affected plugin endpoints via server-level configuration or disable vulnerable features until the update can be applied.
