      "value": "tj-actions/branch-names is a Github action to retrieve branch or tag names with support for all events. The `tj-actions/branch-names` GitHub Actions improperly references the `github.event.pull_request.head.ref` and `github.head_ref` context variables within a GitHub Actions `run` step. The head ref variable is the branch name and can be used to execute arbitrary code using a specially crafted branch name. As a result an attacker can use this vulnerability to steal secrets from or abuse `GITHUB_TOKEN` permissions. This vulnerability has been addressed in version 7.0.7. Users are advised to upgrade. There are no known workarounds for this vulnerability."

      "value": "tj-actions/branch-names es una acci\u00f3n de Github para recuperar nombres de ramas o etiquetas con soporte para todos los eventos. Las GitHub Actions `tj-actions/branch-names` hacen referencia incorrectamente a las variables de contexto `github.event.pull_request.head.ref` y `github.head_ref` dentro de un paso de `ejecuci\u00f3n` de GitHub Actions. La variable head ref es el nombre de la rama y se puede usar para ejecutar c\u00f3digo arbitrario usando un nombre de rama especialmente manipulado. Como resultado, un atacante puede utilizar esta vulnerabilidad para robar secretos o abusar de los permisos \"GITHUB_TOKEN\". Esta vulnerabilidad se ha solucionado en la versi\u00f3n 7.0.7. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad."
