Descriptions

In the git-tag-annotation-action (open source GitHub Action) before version 1.0.1, an attacker can execute arbitrary (*) shell commands if they can control the value of [the `tag` input] or manage to alter the value of [the `GITHUB_REF` environment variable]. The problem has been patched in version 1.0.1. If you don't use the `tag` input you are most likely safe. The `GITHUB_REF` environment variable is protected by the GitHub Actions environment so attacks from there should be impossible. If you must use the `tag` input and cannot upgrade to `> 1.0.0` make sure that the value is not controlled by another Action.

En la git-tag-annotation-action (GitHub Action de código abierto) versiones anteriores a 1.0.1, un atacante puede ejecutar comandos de shell arbitrarios (*) si puede controlar el valor de [the "tag" input] o lograr alterar la valor de [the "GITHUB_REF" environment variable]. El problema ha sido parcheado en la versión 1.0.1. Si no usa la entrada "tag", lo más probable es que esté seguro. La variable de entorno "GITHUB_REF" está protegida por el entorno de GitHub Actions, por lo que los ataques desde allí deberían ser imposibles. Si debe utilizar la entrada "tag" y no puede actualizar a "versiones posteriores a 1.0.0", asegúrese de que el valor no esté controlado por otra Acción
