Our most visited CVE page for the year was, a Denial of Service vulnerability in JSON-Java. This flaw, discovered by ClusterFuzz, exploited a parser bug, allowing a small input string to trigger extensive memory usage. The severity remains high due to its potential impact on unpatched binaries. The issue has been fixed via this PR.
