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 WP Custom Admin Interface plugin is installedCheck the WordPress plugins directory or use wp-cli: wp plugin list --status=active --format=csv | grep 'wp-custom-admin-interface'Affected if Plugin is active and installed
-
Determine the installed plugin versionCheck the plugin header in wp-content/plugins/wp-custom-admin-interface/plugin.php or use: wp plugin get wp-custom-admin-interface --format=jsonAffected if Version is 7.42 or lower (any version up to and including 7.42)
-
Inspect plugin admin settings pages for user input fieldsNavigate to the plugin settings in WordPress admin panel under the plugin menu and examine any text input fields, custom admin label fields, or customization options that accept user-provided textAffected if Plugin has input fields that save and display user-supplied text without visible sanitization
-
Check browser DOM for unsanitized outputUse browser developer tools (Elements/Inspector panel) to view the HTML source of plugin-rendered admin pages and check if user input appears as raw text without HTML entity encodingAffected if User input is rendered as raw HTML or unescaped text in the DOM
If the plugin is active with version 7.42 or lower and contains user input fields that display unsanitized content in the browser DOM, the environment is affected by this XSS vulnerability.

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 WP Custom Admin Interface to the latest patched version once available. In the interim, implement output encoding using WordPress sanitization functions (esc_html, esc_attr, wp_kses) and consider adding Content-Security-Policy headers to mitigate XSS execution.
