Securing GitHub Actions with William Woodruff

William Woodruff discussed his project, Zizmor, a security linter designed to help developers identify and fix vulnerabilities within their GitHub Actions workflows. This tool addresses inherent security risks in GitHub Actions, such as injection vulnerabilities, permission issues, and mutable tags, by providing static analysis and remediation guidance. Fresh off the heels of the tj-actions/changed-files backdoor, this is a great topic with some things everyone can do right away.
