      "value": "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."

El problema ha sido parcheado en la versi\u00f3n 1.0.1. Si no usa la entrada \"tag\", lo m\u00e1s probable es que est\u00e9 seguro. La variable de entorno \"GITHUB_REF\" est\u00e1 protegida por el entorno de GitHub Actions, por lo que los ataques desde all\u00ed deber\u00edan ser imposibles. Si debe utilizar la entrada \"tag\" y no puede actualizar a \"versiones posteriores a 1.0.0\", aseg\u00farese de que el valor no est\u00e9 controlado por otra Acci\u00f3n"
