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 Sparkle FSE theme is installedIn WordPress admin dashboard, go to Appearance > Themes and look for Sparkle FSE in the list of installed themesAffected if Sparkle FSE theme is installed and activated on the WordPress site
-
Determine the installed theme versionCheck the theme styles.css file in wp-content/themes/sparkle-fse/ for the Version header, or view the theme details in Appearance > ThemesAffected if The installed version matches or falls within the affected version range of the theme (compare to the version that contains the authorization fix)
-
Inspect admin AJAX endpoints for authorizationExamine theme PHP files for admin-ajax.php hooks and verify that callback functions include capability checks (current_user_can) or nonce verification before performing sensitive operationsAffected if Theme AJAX handlers lack proper authorization checks on sensitive actions
-
Check theme settings pages for access controlReview theme options or settings pages (usually in inc/ or classes/ folders) and verify that functions modifying theme settings or executing sensitive operations validate user capabilitiesAffected if Theme settings or configuration functions are accessible without verifying user permissions
-
Test for unauthorized administrative function accessAs a non-administrator user or logged-out visitor, attempt to access theme-specific AJAX actions or functions that should require admin privileges and observe if requests succeed without authorization errorsAffected if Requests to theme administrative functions succeed without proper capability verification
A site is affected if it has Sparkle FSE theme installed and theme functions handling sensitive operations lack proper authorization checks, allowing unauthenticated or lower-privileged users to access admin functionality.

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 Sparkle FSE when available, or add proper authorization checks to all sensitive functions within the theme; implement a WAF rule as a temporary protective measure.
