CVE-2024-54462

Unsanitized Filenames in Flutter package image_picker_android Allow File Overwrites

The file names constructed within image_picker are missing sanitization checks leaving them vulnerable to malicious document providers. This may result in cases where a user with a malicious document provider installed can select an image file from that provider while using your app and could potentially override internal files in your app cache. Issue patched in 0.8.12+18. It is recommended to update to the latest version of image_picker_android that contains the changes to address this vulnerability.

Dart SDK and Flutter SDK have Zip slip in Dart Pub package extraction

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 extracted outside the destination directory in the `PUB_CACHE`. A fix has been landed in commit 26c6985c742593d081f8b58450f463a584a4203a. By normalizing the file path before writing file, the attacker can no longer traverse up via a symlink. This patch is released in Dart 3.11.0 and Flutter 3.41.0.vAll packages on pub.dev have been vetted for this vulnerability. New packages are no longer allowed to contain symlinks. The pub client itself doesn't upload symlinks, but duplicates the linked entry, and has been doing this for years. Those whose dependencies are all from pub.dev, third-party repositories trusted to not contain malicious code, or git dependencies are not affected by this vulnerability.

CVE-2022-3095

Incorrect parsing of the backslash characters in Dart library

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.
