Description Vipul Nair 2022-02-08 08:45:12 UTC
twisted is an event-driven networking engine written in Python. In affected versions twisted exposes cookies and authorization headers when following cross-origin redirects. This issue is present in the `twisted.web.RedirectAgent` and `twisted.web.BrowserLikeRedirectAgent` functions. Users are advised to upgrade. There are no known workarounds.
