WP Import – Ultimate CSV XML Importer for WordPress <= 7.35 - Authenticated (Contributor+) Server-Side Request Forgery via Bitly Shortlink Bypass
The WP Import – Ultimate CSV XML Importer for WordPress plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 7.35. This is due to inadequate validation of the resolved URL after following Bitly shortlink redirects in the upload_function() method. While the initial URL is validated using wp_http_validate_url(), when a Bitly shortlink is detected, the unshorten_bitly_url() function follows redirects to the final destination URL without re-validating it. This makes it possible for authenticated attackers with Contributor-level access or higher to make the server perform HTTP requests to arbitrary internal endpoints, including localhost, private IP ranges, and cloud metadata services (e.g., 169.254.169.254), potentially exposing sensitive internal data.
