AppSec Overflow 2026

Contrast's 2026 application threat report reveals the fundamental imbalance between attackers and defenders, based on trillions of real-world observations from inside running applications.

Attackers aren't guessing anymore. They're using AI to reach real vulnerable code in hours, while fixes still take months. Most security tools never see it happen.

AppSec Overflow 2026 draws on runtime telemetry from inside thousands of live applications and APIs, giving security leaders the visibility they've been missing.

• 42 viable attacks per app every month, confirmed reaching real code
• Attackers touch running applications once every 4 minutes
• 22 serious vulnerabilities per app, and only 3.4 fixed a month
• Exploits land in hours while patching takes 92 days
• Three AI scanners, same code, 5% agreement
• Top attack types by industry and language

"AI has changed the math behind application security. This report shows defenders what actually works now."
