CVE-2019-8322

CVE-2019-8322 describes an escape sequence injection vulnerability in RubyGems versions 2.6 through 3.0.2, affecting various Debian and openSUSE distributions. The flaw arises because the 'gem owner' command directly outputs API responses to stdout, allowing a crafted response to inject malicious escape sequences. With a CVSS score of 7.5 (High), this vulnerability is remotely exploitable with low attack complexity and can lead to high integrity impacts, though confidentiality and availability are not directly affected. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
