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.
-
Locate Pearl theme version fileAccess the theme's style.css file (typically at /wp-content/themes/pearl/style.css) or theme.json in the theme root directory. Look for the 'Version:' comment or 'version' field.Affected if The version listed is 3.4.10 or lower (e.g., 3.4.9, 3.4.8, etc.)
-
Confirm theme is activeLog into the WordPress admin dashboard and navigate to Appearance > Themes to verify the Pearl theme is currently activated on the site.Affected if The Pearl - Corporate Business theme is active and the version is 3.4.10 or below
-
Identify file path handling endpointsSearch the theme's PHP files for functions that handle file paths: include(), include_once(), require(), require_once(), file_get_contents(), fopen(), readfile(), or similar. Look for instances where these functions accept parameters without sanitization (e.g., $_GET, $_POST, or request variables used directly in file paths).Affected if Any PHP file in the theme uses request parameters to construct file paths without validation such as basename(), realpath(), or allow_url_fopen restrictions
-
Test for directory traversal vulnerabilityIf a file path parameter is identified, attempt a controlled test using a path like ../../../../../../etc/passwd or ..%2F..%2F..%2F..%2F..%2Fetc%2Fpasswd on the suspected endpoint. Monitor whether the server returns file contents or an error revealing file existence.Affected if The application returns content from files outside the web root directory, or error messages disclose server file paths
The site is affected if the Pearl - Corporate Business theme version is 3.4.10 or below AND the theme contains file path parameters that can be manipulated via URL or request input to traverse directories and read arbitrary files.

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 patched version of the Pearl - Corporate Business theme; alternatively, implement strict input validation and disable allow_url_fopen to prevent directory traversal attacks.
