Descriptions

The implementation of backslash parsing in the Dart URI class for versions prior to 2.18 and Flutter versions prior to 3.30 differs from the WhatWG URL standards. Dart uses the RFC 3986 syntax, which creates incompatibilities with the '\' characters in URIs, which can lead to auth bypass in webapps interpreting URIs. We recommend updating Dart or Flutter to mitigate the issue.

La implementación del análisis de barra invertida en la clase Dart URI para versiones anteriores a 2.18 y versiones de Flutter anteriores a 3.30 difiere de los estándares de URL de WhatWG. Dart utiliza la sintaxis RFC 3986, que crea incompatibilidades con los caracteres '\' en los URI, lo que puede provocar una omisión de autenticación en las aplicaciones web que interpretan los URI. Recomendamos actualizar Dart o Flutter para mitigar el problema.
