About this tag
GitHub Actions is a CI/CD platform that automates software builds, tests, and deployments directly from GitHub repositories. Recent discussions on WindowsForum highlight critical security and governance challenges around GitHub Actions, including supply-chain attacks like Cordyceps and Miasma that exploit workflow trust assumptions, prompt injection vulnerabilities in AI agents such as Claude Code and Copilot CLI that can leak CI/CD secrets, and automated threats like hackerbot-claw that weaponize misconfigured workflows. These incidents underscore the importance of securing workflow files, managing token permissions, and treating build pipelines as part of the attack surface. For developers and IT teams, GitHub Actions requires careful configuration to prevent unauthorized access and credential exposure.
