      "value": "A regular expression based DoS vulnerability in Action Dispatch <6.0.6.1,< 6.1.7.1, and <7.0.4.1. Specially crafted cookies, in combination with a specially crafted X_FORWARDED_HOST header can cause the regular expression engine to enter a state of catastrophic backtracking. This can cause the process to use large amounts of CPU and memory, leading to a possible DoS vulnerability All users running an affected release should either upgrade or use one of the workarounds immediately."

      "value": "Una vulnerabilidad DoS basada en expresiones regulares en Action Dispatch anterior a 6.0.6.1, anterior a 6.1.7.1 y anterior a 7.0.4.1. Las cookies especialmente diseñadas, en combinación con un encabezado X_FORWARDED_HOST especialmente diseñado, pueden hacer que el motor de expresiones regulares entre en un estado de retroceso catastrófico. Esto puede hacer que el proceso utilice grandes cantidades de CPU y memoria, lo que lleva a una posible vulnerabilidad DoS. Todos los usuarios que ejecuten una versión afectada deben actualizar o usar una de las soluciones alternativas inmediatamente."
