CVE-2019-8323

CVE-2019-8323 is a high-severity vulnerability affecting RubyGems versions 2.6 through 3.0.2, as well as various Debian and openSUSE distributions. It allows for escape sequence injection due to Gem::GemcutterUtilities#with_response outputting API responses directly to stdout, enabling an attacker to manipulate the output if the API response is altered. The CVSSv3 score is 7.5 (High), indicating a network-exploitable vulnerability with low attack complexity and high impact on integrity. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
