Can Copilot Fix Its Own Security Findings? Testing GitHub Agentic Autofix

GitHub Copilot now features an agentic Autofix capable of end-to-end remediation by exploring repositories and opening draft pull requests. While ambitious, the effectiveness of these fixes depends on CI controls and human oversight. However, Wiz Research revealed a critical failure at Snowflake, where a Copilot Autofix commit deleted essential security patterns. This vulnerability allowed an autonomous agent to compromise Snowflake's internal Jira via a GitHub issue, highlighting new risks associated with AI-generated code in CI/CD pipelines.
