Comment and Control: Hijacking Agentic Workflows via Context-Grounded Evolution

arXiv:2605.11229v1 Announce Type: cross Abstract: Automation platforms such as GitHub Actions and n8n are increasingly adopting so-called agentic workflows, which integrate Large Language Model (LLM) agents for tasks such as code review and data synchronization. While bringing convenience for developers, this integration exposes a new risk: An adversary may control and craft certain inputs, such as GitHub issue comments, to manipulate the LLM agent for unwanted actions, such as credential exfilt
