{"id":"CVE-2022-3095","details":"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.","modified":"2026-04-12T06:01:12.840562Z","published":"2022-10-27T16:15:09.600Z","references":[{"type":"ADVISORY","url":"https://github.com/dart-lang/sdk/blob/master/CHANGELOG.md#2182---2022-09-28"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dart-lang/sdk","events":[{"introduced":"0"},{"fixed":"63c2197b976931c6472d9dc9574f98ff2ae9408c"}],"database_specific":{"cpe":"cpe:2.3:a:dart:dart_software_development_kit:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.18.0"}],"source":"CPE_FIELD"}}],"versions":["1.11.0","1.11.0-dev.2.0","1.11.0-dev.3.0","1.11.0-dev.4.0","1.11.0-dev.5.0","1.11.0-dev.5.1","1.11.0-dev.5.2","1.11.0-dev.5.3","1.11.0-dev.5.4","1.11.0-dev.5.5","1.11.0-dev.5.6","1.11.0-dev.5.7","1.11.1","1.11.2","1.11.3","1.12.0","1.12.1","1.12.2","1.13.0","1.13.1","1.13.2","1.14.0","1.14.1","1.14.2","1.15.0","1.16.0","1.16.1","1.17.0","1.17.1","1.18.0","1.18.1","1.19.0","1.19.1","1.20.0","1.20.1","1.21.0","1.21.1","1.22.0","1.22.1","1.23.0","1.24.0","1.24.1","1.24.2","1.24.3","2.0.0","2.1.0","2.1.1","2.10.0","2.10.1","2.10.2","2.10.3","2.10.4","2.10.5","2.12.0","2.12.1","2.12.2","2.12.3","2.12.4","2.13.0","2.13.1","2.13.3","2.13.4","2.14.0","2.14.1","2.14.2","2.14.3","2.14.4","2.15.0","2.15.1","2.16.0","2.16.1","2.16.2","2.17.0","2.17.1","2.17.3","2.17.5","2.17.6","2.17.7","2.2.0","2.3.0","2.3.1","2.3.2","2.4.0","2.4.1","2.5.0","2.5.1","2.5.2","2.6.0","2.6.1","2.7.0","2.7.1","2.7.2","2.8.1","2.8.2","2.8.3","2.8.4","2.9.0","2.9.1","2.9.2","2.9.3"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-3095.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/flutter/flutter","events":[{"introduced":"0"},{"fixed":"18a827f3933c19f51862dde3fa472197683249d6"}],"database_specific":{"cpe":"cpe:2.3:a:flutter:flutter:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"3.3.3"}],"source":"CPE_FIELD"}}],"versions":["0.0.10","0.0.11","0.0.12","0.0.13","0.0.14","0.0.15","0.0.16","0.0.17","0.0.18","0.0.19","0.0.20","0.0.21","0.0.6","0.0.7","0.0.8","0.0.9","1.17.0-dev.0.0","1.17.0-dev.1.0","1.17.0-dev.2.0","1.17.0-dev.3.0","1.17.0-dev.4.0","1.17.0-dev.5.0","1.18.0-10.0.pre","1.18.0-11.0.pre","1.18.0-12.0.pre","1.18.0-13.0.pre","1.18.0-6.0.pre","1.18.0-7.0.pre","1.18.0-8.0.pre","1.18.0-dev.0.0","1.18.0-dev.1.0","1.18.0-dev.2.0","1.18.0-dev.3.0","1.18.0-dev.4.0","1.18.0-dev.5.0","1.19.0-0.0.pre","1.19.0-1.0.pre","1.19.0-2.0.pre","1.19.0-3.0.pre","1.19.0-5.0.pre","1.20.0-0.0.pre","1.20.0-2.0.pre","1.20.0-7.0.pre","1.21.0-1.0.pre","1.21.0-5.0.pre","1.21.0-7.0.pre","1.21.0-9.0.pre","1.22.0-1.0.pre","1.22.0-9.0.pre","1.23.0-13.0.pre","1.23.0-18.0.pre","1.23.0-3.0.pre","1.23.0-7.0.pre","1.24.0-1.0.pre","1.24.0-3.0.pre","1.24.0-6.0.pre","1.24.0-7.0.pre","1.25.0-4.0.pre","1.25.0-8.0.pre","1.26.0-1.0.pre","1.26.0-12.0.pre","1.26.0-17.0.pre","1.27.0-1.0.pre","1.27.0-4.0.pre","1.27.0-8.0.pre","2.1.0-10.0.pre","2.1.0-12.0.pre","2.10.0-0.0.pre","2.12.0-4.0.pre","2.2.0-10.0.pre","2.3.0-0.0.pre","2.3.0-1.0.pre","2.3.0-12.0.pre","2.3.0-16.0.pre","2.4.0-0.0.pre","2.4.0-4.0.pre","2.5.0-1.0.pre","2.5.0-5.0.pre","2.5.0-6.0.pre","2.6.0-0.0.pre","2.6.0-11.0.pre","2.6.0-5.0.pre","2.9.0-0.0.pre","3.0.0-0.0.pre","3.3.0","3.3.0-0.0.pre","3.3.0-0.1.pre","3.3.0-0.2.pre","3.3.0-0.3.pre","3.3.0-0.4.pre","3.3.0-0.5.pre","3.3.1","3.3.2","flutter-0.0-candidate.1","v0.0.10","v0.0.11","v0.0.12","v0.0.13","v0.0.14","v0.0.15","v0.0.16","v0.0.17","v0.0.18","v0.0.19","v0.0.20","v0.0.20-alpha","v0.0.21","v0.0.22","v0.0.23","v0.0.24","v0.0.6","v0.0.7","v0.0.8","v0.0.9","v0.1.0","v0.1.1","v0.1.2","v0.1.3","v0.1.4","v0.1.5","v0.1.6","v0.1.7","v0.1.8","v0.1.9","v0.10.0","v0.10.1","v0.10.2","v0.11.0","v0.11.1","v0.11.10","v0.11.11","v0.11.12","v0.11.13","v0.11.2","v0.11.3","v0.11.4","v0.11.5","v0.11.6","v0.11.7","v0.11.8","v0.11.9","v0.2.0","v0.2.1","v0.2.10","v0.2.11","v0.2.2","v0.2.3","v0.2.4","v0.2.5","v0.2.6","v0.2.7","v0.2.8","v0.2.9","v0.3.0","v0.3.1","v0.3.2","v0.3.3","v0.3.4","v0.3.5","v0.3.6","v0.4.0","v0.4.1","v0.4.2","v0.4.3","v0.4.4","v0.5.0","v0.5.1","v0.5.2","v0.5.3","v0.5.4","v0.5.5","v0.5.6","v0.5.7","v0.5.8","v0.6.0","v0.6.1","v0.6.2","v0.7.0","v0.7.1","v0.7.2","v0.7.3","v0.7.4","v0.7.5","v0.8.0","v0.8.1","v0.8.2","v0.8.3","v0.8.4","v0.8.5","v0.8.6","v0.8.7","v0.9.0","v0.9.1","v0.9.2","v0.9.3","v0.9.4","v0.9.5","v0.9.6","v1.0.0","v1.1.0","v1.1.1","v1.1.2","v1.1.3","v1.1.4","v1.1.5","v1.1.6","v1.1.7","v1.1.8","v1.1.9","v1.10.0","v1.10.1","v1.10.10","v1.10.11","v1.10.12","v1.10.13","v1.10.14","v1.10.15","v1.10.16","v1.10.2","v1.10.3","v1.10.4","v1.10.5","v1.10.6","v1.10.7","v1.10.8","v1.10.9","v1.11.0","v1.12.0","v1.12.1","v1.12.10","v1.12.11","v1.12.12","v1.12.13","v1.12.14","v1.12.15","v1.12.16","v1.12.2","v1.12.3","v1.12.4","v1.12.5","v1.12.6","v1.12.7","v1.12.8","v1.12.9","v1.13.0","v1.13.1","v1.13.2","v1.13.3","v1.13.4","v1.13.5","v1.13.6","v1.13.7","v1.13.8","v1.13.9","v1.14.0","v1.14.1","v1.14.2","v1.14.3","v1.14.4","v1.14.5"
