CVE-2021-22568

Dart - Publishing to third-party package repositories may expose pub.dev credentials

Description

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.
