Summary

Rapid7 reported that high- and critical-severity vulnerability disclosures doubled year on year to 8,539 in Q2 2026, while newly exploited vulnerabilities rose 8% to 40. The analysis links the pressure to AI-assisted discovery and exploitation, as well as insecure code produced through vibe coding, and recommends prioritising exposure over severity scores alone.

Why it matters

Security and development teams need exposure-aware triage and continuous controls around AI-generated code rather than relying only on periodic, severity-based remediation.
