AI-Driven Command Injection Vulnerability Exposes Snowflake Jira Credentials A critical command injection vulnerability was discovered in Snowflake's GitHub Actions workflow, allowing unauthenticated attackers to execute arbitrary commands. The flaw was introduced by an AI coding assistant, GitHub Copilot Autofix, which altered the code on June 18, 2026. This change enabled attackers to exploit the vulnerability by opening GitHub issues with specially crafted titles, leading to the exposure of internal Jira credentials. Wiz Research's Red Agent identified the vulnerability on June 23, 2026, and disclosed it to Snowflake, which remediated the issue the same day. No evidence of malicious exploitation has been found, and the affected credentials were rotated shortly after. This incident highlights the risks associated with AI-assisted code generation in security-sensitive environments. 11 sources 68
