# Wiz Red Agent Finds Critical GitHub Copilot Autofix Vulnerability in Snowflake

> Wiz says its autonomous security tool, Red Agent, found a critical flaw in Snowflake's GitHub Actions setup that GitHub's own AI had already looked at and cleared. The bug was a shell injection: a crafted GitHub issue title could execute arbitrary commands in the pipeline, a classic path to compromising a CI/CD system. The uncomfortable detail is that GitHub Advanced Security and Copilot Autofix both analyzed the vulnerable code and missed it, and the flaw lived for five days after a patch before Wiz's agent surfaced it. In other words, automated AI security checks gave the code a pass that it did not deserve. The episode cuts two ways for the industry's favorite promise that AI will secure software. Autonomous agents clearly can hunt down real, subtle vulnerabilities faster than humans, but the same automation can also wave through dangerous code with false confidence, which is a reminder that these tools augment review rather than replace it.
