      "value": "PHP_CodeSniffer tokenizes PHP files and detects violations of a defined set of coding standards. Prior to versions 3.13.6 and 4.0.2, PHP_CodeSniffer contains a command injection vulnerability in the code that generates the Gitblame, Hgblame, and Svnblame report formats. As a result, running PHP_CodeSniffer over untrusted files, for example in a continuous integration pipeline that scans pull requests, or on a developer machine reviewing third party code, could result in attacker controlled shell commands being executed when the Gitblame, Hgblame, or Svnblame report processes a file whose name contains shell metacharacters. Users using the default Full report, or any of the other non-blame reports, are not affected. Users on a runtime platform which does not allow filenames to contain shell metacharacters, such as \" and ;, are not affected. This issue is fixed in versions 3.13.6 and 4.0.2."

      "value": "PHP_CodeSniffer tokeniza archivos PHP y detecta violaciones de un conjunto definido de estándares de codificación. Antes de las versiones 3.13.6 y 4.0.2, PHP_CodeSniffer contiene una vulnerabilidad de inyección de comandos en el código que genera los formatos de informe Gitblame, Hgblame y Svnblame. Como resultado, ejecutar PHP_CodeSniffer sobre archivos no confiables, por ejemplo en una tubería de integración continua que escanea solicitudes de extracción, o en una máquina de desarrollador revisando código de terceros, podría resultar en la ejecución de comandos de shell controlados por el atacante cuando el informe Gitblame, Hgblame o Svnblame procesa un archivo cuyo nombre contiene metacaracteres de shell. Los usuarios que utilizan el informe Full predeterminado, o cualquiera de los otros informes no-blame, no se ven afectados. Los usuarios en una plataforma de tiempo de ejecución que no permite que los nombres de archivo contengan metacaracteres de shell, como ” y ;, no se ven afectados. Este problema está solucionado en las versiones 3.13.6 y 4.0.2."
