At DARPA's AIxCC finals in August 2025, AI systems patched 68% of vulnerabilities they found — up from 25% at semifinals. Here's how the approaches differ and why validation still matters most.
CVE-2021-44228 scored a perfect CVSS 10.0 and hit CISA's Known Exploited Vulnerabilities list the day it was published — the root cause hasn't gone away.
Keep-alive and HTTP/2 multiplexing cut handshake overhead but hold server resources open per connection — Slowloris and 2023's Rapid Reset attacks both exploited exactly that tradeoff.
CVE-2025-59536 (CVSS 8.7) let a single malicious commit auto-approve MCP servers in Claude Code, no install click required. Registries need the same controls as package managers.
