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 Cart Lift plugin installationAccess your WordPress admin dashboard and navigate to Plugins > Installed Plugins. Locate 'Cart Lift' by RexTheme and note the installed version number.Affected if Cart Lift plugin is installed and active
-
Compare installed version to affected releasesCompare your installed version number to any publicly disclosed affected versions. Check the RexTheme changelog or security advisories for version information.Affected if Installed version falls within a vulnerable version range
-
Identify plugin user input formsReview the Cart Lift plugin settings and frontend forms to locate all user input fields (checkout fields, customer info fields, custom fields, etc.) that accept and store user data.Affected if The plugin accepts user-supplied input through any form fields
-
Inspect stored data for lack of sanitizationSubmit test input containing HTML/JavaScript characters (e.g., <script>alert(1)</script>) through plugin forms, then view the stored data in the admin backend or frontend to see if the input is rendered as raw HTML rather than escaped.Affected if User input is stored and displayed without proper output encoding (input renders as executable HTML/JavaScript)
-
Verify admin access to stored submissionsNavigate to Cart Lift order/submission admin pages and examine how customer-provided data is displayed. Check if data appears in raw form or is properly escaped when rendered in HTML.Affected if Stored user data displays without HTML entity encoding when viewed
You are affected if Cart Lift plugin is installed, stores user input, and renders that input without escaping HTML/JavaScript characters (allowing script execution upon page view).
Generated from the published advisory. Verify against your own 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 dataUpdate to the latest version of Cart Lift plugin that addresses this vulnerability, or implement proper server-side input validation and output encoding for all user-supplied data.
