Versions prior to 2.1.1 contain an RCE vulnerability in the .github/workflows/regenerate-migrations.yml workflow. The workflow uses the pull_request_target trigger to run with full GITHUB_TOKEN write permissions, copies attacker-controlled files from untrusted pull requests into the trusted runner workspace via git show, and then executes python manage.py makemigrations, which imports Django model modules including attacker-controlled website/models.py at runtime. Any module-level Python code in the attacker's models.py is executed during import, enabling arbitrary code execution in the privileged CI environment with access to GITHUB_TOKEN and repository secrets. The attack is triggerable by any external contributor who can open a pull request, provided a maintainer applies the regenerate-migrations label, potentially leading to secret exfiltration, repository compromise, and supply chain attacks. A patch for this issue is expected to be released in version 2.1.1."}, {"lang": "es", "value": "OWASP BLT es una plataforma de pruebas de QA y divulgaci\u00f3n de vulnerabilidades que abarca sitios web, aplicaciones, repositorios git y m\u00e1s. Las versiones anteriores a la 2.1.1 contienen una vulnerabilidad RCE en el flujo de trabajo .github/workflows/regenerate-migrations.yml. El flujo de trabajo utiliza el disparador pull_request_target para ejecutarse con permisos de escritura completos de GITHUB_TOKEN, copia archivos controlados por el atacante de solicitudes de extracci\u00f3n no confiables al espacio de trabajo del ejecutor confiable a trav\u00e9s de git show, y luego ejecuta python manage.py makemigrations, que importa m\u00f3dulos de modelo de Django incluyendo website/models.py controlado por el atacante en tiempo de ejecuci\u00f3n. Cualquier c\u00f3digo Python a nivel de m\u00f3dulo en el models.py del atacante se ejecuta durante la importaci\u00f3n, lo que permite la ejecuci\u00f3n de c\u00f3digo arbitrario en el entorno CI privilegiado con acceso a GITHUB_TOKEN y a los secretos del repositorio.
