CVE-2024-21654: rubygems: MFA bypass through password reset function could allow account takeover

Severity: Critical

CVSS Score: 9.8

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. This vulnerability has been patched in commit 0b3272a.
