CVE-2011-4121 describes a critical vulnerability in the OpenSSL extension of Ruby (Git trunk) versions released between September 1 and November 3, 2011, where private RSA key generation consistently used an exponent value of '1'. This flaw, rated 9.8 Critical (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), allows a remote attacker to bypass or corrupt the integrity of services relying on strong RSA keys, due to the trivial nature of an exponent of '1'. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
