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 plugin installationCheck the WordPress plugins directory or admin panel for the presence of 'Ultimate Store Kit' or 'bdthemes Ultimate Store Kit' pluginAffected if Plugin is installed and active on the WordPress site
-
Identify installed versionAccess the WordPress admin plugins page, click on the plugin details, or inspect the main plugin file header for the version numberAffected if Installed version is 2.4.0 or lower (any version up to and including 2.4.0)
-
Verify authentication requirementsCheck WordPress user registration settings and available user roles on the site. Determine if lower-privileged accounts (subscriber, contributor, customer) can access the siteAffected if Site allows user registration or has existing user accounts beyond administrator
-
Inspect for compromise indicatorsReview web server error logs and access logs for patterns related to PHP object injection attempts, such as serialized PHP objects in request parameters, or suspicious PHP files created in plugin directoriesAffected if Suspicious serialized data in HTTP requests or unknown PHP files exist in the plugin directory
-
Check for unauthorized code executionExamine plugin directories for newly created or modified PHP files with obfuscated code, or review site for unexpected administrative accounts or cron jobsAffected if Unknown PHP files present, new admin accounts created without action, or unfamiliar scheduled tasks exist
A site is affected if it runs Ultimate Store Kit plugin version 2.4.0 or lower and permits authenticated user access, enabling the PHP Object Injection attack vector.

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.
dbcve · scopedUpdate to the latest version of Ultimate Store Kit Elementor Addons immediately. If no patched version is available, disable the plugin until a fix is released. Review the site for any indicators of compromise.
Version higher than 2.4.0 (e.g., 2.4.1 or latest available)
- 1. Update bdthemes Ultimate Store Kit Elementor Addons to the latest available version from the WordPress plugin repository or bdthemes official sources
- 2. Verify the update was successfully applied by checking the plugin version in WordPress admin
- 3. Clear any caching systems if used (site cache, CDN cache)
- 4. Test critical e-commerce functionality on the site to ensure the update did not break existing features
