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 • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00048.html https://github.com/corydolphin/flask-cors/releases/tag/3.0.9 https://www.debian.org/security/2020/dsa-4775 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
