CVE-2022-3095: 
NixOS vulnerability analysis and mitigation

The CVE-2022-3095 vulnerability affects the Dart URI class implementation in versions prior to 2.18 and Flutter versions prior to 3.30. The issue stems from Dart's use of RFC 3986 syntax for URI parsing, which creates incompatibilities with backslash characters in URIs (NVD).

The vulnerability is related to the implementation of backslash parsing in the Dart URI class. The core issue lies in the difference between Dart's implementation, which follows RFC 3986 syntax, and the WhatWG URL standards. This discrepancy in handling backslash characters can lead to security implications. The vulnerability has been assigned a CVSS v3.1 base score of 9.8 (CRITICAL) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (NVD).

The vulnerability can potentially lead to authentication bypass in web applications that interpret URIs. This is particularly concerning given the critical CVSS score and the potential for unauthorized access to affected systems (NVD).

The recommended mitigation is to update Dart to version 2.18 or later, or Flutter to version 3.30 or later. These updates address the URI parsing inconsistency and implement proper handling of backslash characters (NVD).
