Descriptions

An issue was discovered in Flask-CORS (aka CORS Middleware for Flask) before 3.0.9. It allows ../ directory traversal to access private resources because resource matching does not ensure that pathnames are in a canonical format.

Se detectó un problema en Flask-CORS (también se conoce como CORS Middleware para Flask) versiones anteriores a 3.0.9. Permite que un salto de directorios ../ acceda a recursos privados porque la coincidencia de recursos no garantiza que los nombres de ruta estén en un formato canónico
