FKIE_CVE-2025-14627

Vulnerability from fkie_nvd - Published: 2026-01-01 17:15 - Updated: 2026-04-15 00:35
Severity ?
6.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
Summary
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.

Esto se debe a una validaci\u00f3n inadecuada de la URL resuelta despu\u00e9s de seguir redirecciones de enlaces cortos de Bitly en el m\u00e9todo \u0027upload_function()\u0027. Si bien la URL inicial se valida usando \u0027wp_http_validate_url()\u0027, cuando se detecta un enlace corto de Bitly, la funci\u00f3n \u0027unshorten_bitly_url()\u0027 sigue las redirecciones a la URL de destino final sin volver a validarla. Esto hace posible que atacantes autenticados con acceso de nivel de Colaborador o superior hagan que el servidor realice peticiones HTTP a endpoints internos arbitrarios, incluyendo localhost, rangos de IP privados y servicios de metadatos en la nube (p. ej., 169.254.169.254), exponiendo potencialmente datos internos sensibles."
