AI-Generated Code Security Audit Workflow 2026 — Lessons From the Copilot Autofix That Opened Snowflake's Jira
On June 18, 2026, PR #1218 in snowflakedb/snowflake-connector-net — co-authored by 'Copilot Autofix powered by AI' — replaced a safe env: + jq parsing pattern with direct string interpolation of an untrusted issue title into a shell run: block. Five days later, Wiz's autonomous Red Agent exploited the resulting script injection from a public GitHub issue, exfiltrated a Jira credential, and read Snowflake's engineering, security compliance, and bug bounty projects. This is a 6-step audit workflow for AI-assisted PRs, built from the actual failure chain: script-injection review, security-gate semantics, AI regression detection, autonomous-agent defense, and remediation.
