Veracode: AI now writes half of all code, but security pass rate stuck at 56%

WeldPond · x · 2026-10-11

Veracode's 2026 GenAI Code Security Report finds AI now writes roughly half of all committed code in adopting organizations, yet the average security pass rate across 100+ models tested since 2023 is stuck at 56%—syntax is nearly perfect, security is not. Even the top model fails nearly one in three security tasks.

A companion webinar (Oct 22) with Chris Wysopal and Jim Manico will cover intent-based coding—giving AI explicit, framework-specific security requirements before generation rather than after—and AI-SAST as a deterministic verification layer for release gates. The report's choice to test models without security-specific prompting is framed as the opening for this approach.
