Descriptions
An issue was discovered in the rack-cors (aka Rack CORS Middleware) gem before 1.0.4 for Ruby. It allows ../ directory traversal to access private resources because resource matching does not ensure that pathnames are in a canonical format.

Permite que un salto de directorio ../ acceda a recursos privados porque la coincidencia de recursos no garantiza que los nombres de ruta estén en formato canónico.
