CVE-2026-22860

Rack is a modular Ruby web server interface. Prior to versions 2.2.22, 3.1.20, and 3.2.5, `Rack::Directory`’s path check used a string prefix match on the expanded path. A request like `/../root_example/` can escape the configured root if the target path starts with the root string, allowing directory listing outside the intended root. Versions 2.2.22, 3.1.20, and 3.2.5 fix the issue.

Summary
  • (es) Rack es una interfaz modular de servidor web Ruby. Antes de las versiones 2.2.22, 3.1.20 y 3.2.5, la verificación de ruta de 'Rack::Directory' utilizaba una coincidencia de prefijo de cadena en la ruta expandida. Una solicitud como '/../root_example/' puede escapar de la raíz configurada si la ruta de destino comienza con la cadena raíz, permitiendo la enumeración de directorios fuera de la raíz prevista. Las versiones 2.2.22, 3.1.20 y 3.2.5 solucionan el problema.
