Intelligence Summary
Researchers describe a prompt-injection technique targeting AI-powered agentic workflows on GitHub. By using a crafted public GitHub issue, an attacker can influence the workflow’s behavior without authentication. The manipulated instructions can cause the workflow to expose data from private repositories. This impacts organizations that integrate AI agents with GitHub for automation or code-related tasks. Teams should audit workflow prompts, apply strict permission boundaries, and avoid letting public content steer access to private data.
Recommended Action
Prioritize immediate review, validate exposure, and patch or mitigate affected systems.
