      "value": "find-my-way is a fast, open source HTTP router, internally using a Radix Tree (aka compact Prefix Tree), supports route params, wildcards, and it's framework independent. A bad regular expression is generated any time one has two parameters within a single segment, when adding a `-` at the end, like `/:a-:b-`. This may cause a denial of service in some instances. Users are advised to update to find-my-way v8.2.2 or v9.0.1. or subsequent versions. There are no known workarounds for this issue."

Se genera una expresi\u00f3n regular incorrecta cada vez que se tienen dos par\u00e1metros dentro de un solo segmento, al agregar un `-` al final, como `/:a-:b-`. Esto puede causar una denegaci\u00f3n de servicio en algunos casos. Se recomienda a los usuarios que actualicen find-my-way a v8.2.2 o v9.0.1 o versiones posteriores. No se conocen workarounds para este problema."
