*** This bug is a security vulnerability *** Private security bug reported: This is similar to but different from #1968443. The issue is on a list with private rosters an attempt to log in to the options page with an email address which is not a list member just returns the options login page with no error, but attempt to login with an email address which is a list member returns the page with a 401 status and an `Authentication failed.` error message. This could be used to fish for membership on a list with private rosters. ** Affects: mailman Importance: Undecided Status: New -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/2015416 Title: Membership information leak through options page.
