      "value": "App::Ack versions through 3.10.0 for Perl read arbitrary files via --files-from in a project .ackrc.\n\nack searches up the directory hierarchy from the current directory for a project .ackrc and loads its options. The project-source option blocklist in App::Ack::ConfigLoader does not include --files-from, so a project .ackrc can set it to a path whose listed files ack then reads and searches. Version 3.10.0 added --follow to the blocklist; --files-from remains accepted.\n\nA project .ackrc committed to an untrusted repository can make ack read files outside the project and print their matching lines."

      "value": "Las versiones de App::Ack hasta la 3.10.0 para Perl leen archivos arbitrarios a través de --files-from en un archivo .ackrc de proyecto.\n\nack busca en la jerarquía de directorios desde el directorio actual un archivo .ackrc de proyecto y carga sus opciones. La lista negra de opciones de origen de proyecto en App::Ack::ConfigLoader no incluye --files-from, por lo que un archivo .ackrc de proyecto puede configurarlo a una ruta cuyos archivos listados ack luego lee y busca. La versión 3.10.0 añadió --follow a la lista negra; --files-from sigue siendo aceptado.\n\nUn archivo .ackrc de proyecto confirmado en un repositorio no confiable puede hacer que ack lea archivos fuera del proyecto e imprima sus líneas coincidentes."
