Versions of phpgt/Dom prior to 4.1.8 expose the GITHUB_TOKEN in the Dom workflow run artifact. The ci.yml workflow file uses actions/upload-artifact@v4 to upload the build artifact. This artifact is a zip of the current directory, which includes the automatically generated .git/config file containing the run's GITHUB_TOKEN. Seeing as the artifact can be downloaded prior to the end of the workflow, there is a few seconds where an attacker can extract the token from the artifact and use it with the GitHub API to push malicious code or rewrite release commits in your repository. Any downstream user of the repository may be affected, but the token should only be valid for the duration of the workflow run, limiting the time during which exploitation could occur. Version 4.1.8 fixes the issue."}, {"lang": "es", "value": "phpgt/Dom proporciona acceso a las API modernas de DOM. Las versiones de phpgt/Dom anteriores a la 4.1.8 exponen el token GITHUB_TOKEN en el artefacto de ejecuci\u00f3n del flujo de trabajo de Dom.

Dado que el artefacto se puede descargar antes de que finalice el flujo de trabajo, un atacante puede extraer el token del artefacto durante unos segundos y usarlo con la API de GitHub para enviar c\u00f3digo malicioso o reescribir las confirmaciones de versiones en el repositorio. Cualquier usuario intermedio del repositorio puede verse afectado, pero el token solo deber\u00eda ser v\u00e1lido mientras dure la ejecuci\u00f3n del flujo de trabajo, lo que limita el tiempo de explotaci\u00f3n.
