The Dart and Flutter SDKs provide software development kits for the Dart programming language. In versions of the Dart SDK prior to 3.11.0 and the Flutter SDK prior to version 3.41.0, when the pub client (`dart pub` and `flutter pub`) extracts a package in the pub cache, a malicious package archive can have files…

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.…

Dart SDK contains the HTTPClient in dart:io library whcih includes authorization headers when handling cross origin redirects. These headers may be explicitly set and contain sensitive information. By default, HttpClient handles redirection logic. If a request is sent to example.com with authorization header and it…

Bidirectional Unicode text can be interpreted and compiled differently than how it appears in editors which can be exploited to get nefarious code passed a code review by appearing benign. An attacker could embed a source that is invisible to a code reviewer that modifies the behavior of a program in unexpected ways.

When using the dart pub publish command to publish a package to a third-party package server, the request would be authenticated with an oauth2 access_token that is valid for publishing on pub.dev. Using these obtained credentials, an attacker can impersonate the user on pub.dev. We recommend upgrading past…

Bad validation logic in the Dart SDK versions prior to 2.12.3 allow an attacker to use an XSS attack via DOM clobbering. The validation logic in dart:html for creating DOM nodes from text did not sanitize properly when it came across template tags.

An improper HTML sanitization in Dart versions up to and including 2.7.1 and dev versions 2.8.0-dev.16.0, allows an attacker leveraging DOM Clobbering techniques to skip the sanitization and inject custom html/javascript (XSS). Mitigation: update your Dart SDK to 2.7.2, and 2.8.0-dev.17.0 for the dev version. If you…
