What happened

Microsoft Threat Intelligence disclosed a prompt-injection vulnerability in the Claude Code GitHub Action that, under specific conditions, could be abused to access workflow secrets. The research details the attack chain, responsible disclosure process, mitigations implemented by Anthropic, and practical guidance for securing AI-powered CI/CD and agentic workflows. The broader feed also highlights related threats to development supply chains — large-scale npm compromise (Miasma), dependency confusion and typosquatting campaigns stealing cloud and CI/CD credentials, a self-propagating Go-basedr
