CVE-2011-4815 describes a denial-of-service vulnerability in Ruby (CRuby) versions prior to 1.8.7-p357. The flaw stems from the way Ruby computes hash values, allowing attackers to trigger predictable hash collisions with crafted input, leading to high CPU consumption in applications utilizing hash tables. With a CVSS score of 7.8 (High), this vulnerability is easily exploitable over the network with low attack complexity, resulting in a complete denial of service. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
