Claude Mythos Preview Discovers 10,000+ 0-Days in Glasswing

**Executive summary:** Anthropic's Project Glasswing using the Claude Mythos model has autonomously discovered and triaged tens of thousands of candidate vulnerabilities—over 10,000 high- or critical-severity zero-days—with thousands confirmed and hundreds awaiting disclosure or patching, including a working exploit against wolfSSL (CVE-2026-5194); the report highlights a widening remediation bottleneck as maintainers struggle to address the surge of AI-generated findings.
