The `-oProxyCommand` flag causes `ssh` to execute the provided command while `#` shell comment causes any other `ssh` arguments to be ignored.\n\nIn `2.62.0`, the remote username information is being validated before being used."}, {"lang": "es", "value": "La versi\u00f3n 2.6.1 y anteriores de la CLI de GitHub son vulnerables a la ejecuci\u00f3n remota de c\u00f3digo a trav\u00e9s de un servidor SSH de codespace malicioso cuando se usan los comandos `gh codespace ssh` o `gh codespace logs`. Esto se ha corregido en la CLI v2.62.0.
