Frontier AI models are collapsing the time between vulnerability disclosure and active exploitation to near-zero, challenging traditional severity-score-based patching programs. According to CrowdStrike’s 2026 Global Threat Report, AI-enabled adversary attacks increased 89% year-over-year, pre-disclosure zero-day exploitation increased 42% year-over-year, and the fastest observed lateral movement breakout time was 27 seconds – figures that invalidate any patching workflow measured in days or weeks. The reported breach of Anthropic’s Claude Mythos model compounds the signal: AI systems are simultaneously accelerating attacker capabilities and becoming targets themselves, forcing security leaders to rethink both their vulnerability management architecture and their AI supply chain risk posture.
