From version 2.0.0 to before version 2.0.1, the SCP middleware in charm.land/wish/v2 is vulnerable to path traversal attacks. A malicious SCP client can read arbitrary files from the server, write arbitrary files to the server, and create directories outside the configured root directory by sending crafted filenames containing ../ sequences over the SCP protocol. This issue has been patched in version 2.0.1."

Desde la versión 2.0.0 hasta antes de la versión 2.0.1, el middleware SCP en charm.land/wish/v2 es vulnerable a ataques de salto de ruta. Un cliente SCP malicioso puede leer archivos arbitrarios del servidor, escribir archivos arbitrarios en el servidor y crear directorios fuera del directorio raíz configurado enviando nombres de archivo manipulados que contengan secuencias .. /  a través del protocolo SCP. Este problema ha sido parcheado en la versión 2.0.1."
