AI-Generated Code Has 2.74x More Vulnerabilities
February 27, 2026 by Asif Waliuddin
AI-generated code contains 2.74 times more exploitable vulnerabilities than human-written code.
Not "slightly more." Not "a marginal increase that better tooling will catch." 2.74x. With 40-62% of AI-generated code containing exploitable flaws like SQL injection and buffer overflows.
That is from multiple independent studies published in the last two weeks -- SoftwareSeni, Cycode, and Apiiro research all converging on the same conclusion.
But here is the number that should change the conversation at your next engineering leadership meeting: Veracode analyzed 1.6 million applications and found that AI-driven development is creating vulnerabilities faster than teams can fix them. Net negative security posture. The tool you adopted to ship faster is generating security debt faster than your team can service it.
The specific findings are worse than the headline:
-- 322% more privilege escalation paths in AI-generated code. Not surface-level bugs a linter catches. Architectural weaknesses baked in at generation time.
-- 40% more hardcoded API keys, passwords, and tokens. AI models reproduce credential patterns from their training data directly into your codebase. Azure key exposure doubled versus human-written code.
-- Open-source vulnerabilities have doubled, per Black Duck, driven primarily by AI-accelerated code contribution volume. This is not just your code. It is every dependency you pull in.
-- Fortune 50 companies with world-class security teams are generating 10,000+ new AI-code security findings per month, per Apiiro. If the most resourced organizations in the world cannot keep up, the rest of us should be paying attention.
And the asymmetry is brutal: AI reduces attacker weaponization time by 90%. You are shipping vulnerabilities 2.74x faster. Attackers are exploiting them 90% faster. The math is not in your favor.
Every team celebrating AI coding velocity should be asking a harder question: what is the actual cost of 2.74x more vulnerabilities per deployment? Because "we shipped faster" does not appear on a breach disclosure.
The Last Mile problem is not deployment speed. It is security debt.
What is your team doing about AI-generated code security? Are you scanning it differently than human-written code? I want to hear what is actually working.
