Sensitive-header disclosure via cross-origin redirect forwarding
Published Feb 18, 2022 · Updated Apr 21, 2025
Information disclosure in Google Dart SDK before 2.16.0 allows remote attackers to obtain sensitive headers through cross-origin redirects. The dart:io HttpClient automatically copies explicitly set authorization, www-authenticate, cookie, and cookie2 headers into redirected requests without excluding a different destination domain. Exposure requires an application to set a sensitive header and accept an attacker-influenced cross-origin redirect, enabling credential or session-token theft.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
