Adopt
The eighth edition of OWASP's flagship web application security list, released January 2026, is based on analysis of 175,000+ CVEs and 500,000+ applications. AI-generated code is susceptible to all of these classic vulnerabilities — studies show it contains 15-18% more vulnerabilities than human-written code.
Key Changes in 2025
- A01 - Broken Access Control — held #1 (3.73% of apps)
- A02 - Security Misconfiguration — rose from #5; SSRF consolidated into A01
- A03 - Software Supply Chain Failures — NEW, expanded from "Vulnerable Components" to cover build systems and distribution infrastructure
- A05 - Injection — fell from #3 but remains easily exploitable
- A10 - Mishandling of Exceptional Conditions — NEW, fail-open logic and data leaks through error handling
Why It Matters for AI-Assisted Development
AI-generated code produces the same classic vulnerabilities humans do — just more of them. The OWASP Top 10 serves as a baseline checklist for reviewing AI output:
- A03 (Supply Chain) is especially relevant given AI's tendency to suggest compromised or nonexistent packages
- A10 (Exceptional Conditions) catches fail-open patterns common in AI-generated error handling
- Semgrep has updated 4,000+ rules mapped to the 2025 edition
Strengths
- Gold standard for web application security since 2003
- Data-driven scoring model (exploitability + impact, not just frequency)
- Universal adoption; drives entire tooling ecosystems
Limitations
- Web-application focused; does not cover AI-specific threats
- Updated only every ~4 years
- Does not address prompt injection, model poisoning, or other LLM threats (see OWASP LLM Top 10)
