No CVSS score yet. EPSS 8.9% chance of exploitation in the next 30 days. Fixed in rubygems-update 2.0.16, 2.2.4, 2.4.7.
RubyGems 2.0.x before 2.0.16, 2.2.x before 2.2.4, and 2.4.x before 2.4.7 does not validate the hostname when fetching gems or making API requests, which allows remote attackers to redirect requests to arbitrary domains via a crafted DNS SRV record, aka a "DNS hijack attack."
