Whereas neither library has been up to date in years, strongSwan has launched an replace to handle the issue in strongMan (CVE-2026-25998).

OpenAI and Paradigm have collectively introduced EVMbench, a benchmark that measures how nicely AI brokers can detect, exploit, and patch high-severity good contract vulnerabilities. “EVMbench attracts on 120 curated vulnerabilities from 40 audits, with most sourced from open code audit competitions,” OpenAI stated. “EVMbench is meant each as a measurement device and as a name to motion.
