      "value": "get-func-name is a module to retrieve a function's name securely and consistently both in NodeJS and the browser. Versions prior to 2.0.1 are subject to a regular expression denial of service (redos) vulnerability which may lead to a denial of service when parsing malicious input. This vulnerability can be exploited when there is an imbalance in parentheses, which results in excessive backtracking and subsequently increases the CPU load and processing time significantly. This vulnerability can be triggered using the following input: '\\t'.repeat(54773) + '\\t/function/i'. This issue has been addressed in commit `f934b228b` which has been included in releases from 2.0.1. Users are advised to upgrade. There are no known workarounds for this vulnerability."

      "value": "get-func-name es un módulo para recuperar el nombre de una función de forma segura y consistente tanto en NodeJS como en el navegador. Las versiones anteriores a la 2.0.1 están sujetas a una vulnerabilidad de denegación de servicio de expresión regular (redos) que puede provocar una denegación de servicio al analizar entradas maliciosas. Esta vulnerabilidad se puede aprovechar cuando hay un desequilibrio entre paréntesis, lo que da como resultado un retroceso excesivo y, posteriormente, aumenta significativamente la carga de la CPU y el tiempo de procesamiento. Esta vulnerabilidad se puede activar utilizando la siguiente entrada: '\\t'.repeat(54773) + '\\t/function/i'. Este problema se solucionó en el commit `f934b228b` que se incluyó en las versiones 2.0.1. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad."
