Security readout for executives and security teams

This flaw can let a malicious gem owner metadata file trigger code execution when someone runs the RubyGems owner command. Business risk is concentrated in developer, build, and release environments that still use old RubyGems versions and interact with untrusted gems. Exposure is most likely in legacy Ruby environments: Ruby 2.2.9 and earlier, 2.3.6 and earlier, 2.4.3 and earlier, 2.5.0 and earlier, or distro-packaged RubyGems/JRuby covered by vendor advisories. Treat this as a legacy build and developer workstation risk. Prioritize remediation where old Ruby toolchains can access internal source, signing keys, package credentials, or production deployment paths. Mitigation focus: Upgrade RubyGems to 2.7.6 or later where feasible.; Apply relevant Ubuntu, Debian, Red Hat, or SUSE Ruby/JRuby security updates.; Avoid running RubyGems ownership queries against untrusted gems on legacy systems..
