CVE-2011-2363 is a critical use-after-free vulnerability in the nsSVGPointList::AppendElement function affecting Mozilla Firefox before 3.6.18, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14. This flaw allows remote attackers to trigger a denial of service or potentially execute arbitrary code through specially crafted SVG element lists involving user-supplied callbacks. With a CVSS score of 10.0, it represents a severe risk due to its network-based attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability. Despite its high severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
