Description Mauro Matteo Cascella 2024-01-15 17:22:32 UTC 
Rubygems.org is the Ruby community's gem hosting service. Rubygems.org users with MFA enabled would normally be protected from account takeover in the case of email account takeover. However, a workaround on the forgotten password form allows an attacker to bypass the MFA requirement and takeover the account.

Unless I am mistaken, this is flaw in the http://rubygems.org service, not in the package.
