CVE-2025-12962
Local Syndication <= 1.5a - Authenticated (Contributor+) Server-Side Request Forgery via Shortcode
Description
The Local Syndication plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.5a via the `url` parameter in the `[syndicate_local]` shortcode. This is due to the use of `wp_remote_get()` instead of `wp_safe_remote_get()` which lacks protections against requests to internal/private IP addresses and localhost. This makes it possible for authenticated attackers, with Contributor-level access and above, to make web requests to arbitrary locations originating from the web application, which can be used to query and modify information from internal services, scan internal networks, and access resources that should not be accessible from external networks.

Action Type Old Value New Value Added Translation Title: Local Syndication de willbontrager, Description: El plugin Local Syndication para WordPress es vulnerable a la Server-Side Request Forgery en todas las versiones hasta la 1.5a, inclusive, a través del parámetro 'url' en el shortcode '[syndicate_local]'. Esto se debe al uso de 'wp_remote_get()' en lugar de 'wp_safe_remote_get()', que carece de protecciones contra peticiones a direcciones IP internas/privadas y localhost. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador y superior, realicen peticiones web a ubicaciones arbitrarias originadas desde la aplicación web, lo que puede utilizarse para consultar y modificar información de servicios internos, escanear redes internas y acceder a recursos que no deberían ser accesibles desde redes externas. -
