      "value": "corydolphin/flask-cors version 4.01 contains a vulnerability where the request path matching is case-insensitive due to the use of the `try_match` function, which is originally intended for matching hosts. This results in a mismatch because paths in URLs are case-sensitive, but the regex matching treats them as case-insensitive. This misconfiguration can lead to significant security vulnerabilities, allowing unauthorized origins to access paths meant to be restricted, resulting in data exposure and potential data leaks."

      "value": "La versi\u00f3n 4.01 de corydolphin/flask-cors contiene una vulnerabilidad donde la coincidencia de rutas de solicitud no distingue entre may\u00fasculas y min\u00fasculas debido al uso de la funci\u00f3n `try_match`, originalmente dise\u00f1ada para la coincidencia de hosts. Esto genera una discrepancia, ya que las rutas en las URL distinguen entre may\u00fasculas y min\u00fasculas, pero la coincidencia de expresiones regulares las trata como si no las tuvieran. Esta configuraci\u00f3n incorrecta puede generar vulnerabilidades de seguridad importantes, permitiendo que or\u00edgenes no autorizados accedan a rutas que deber\u00edan estar restringidas, lo que resulta en la exposici\u00f3n y posibles fugas de datos."
