GitHub's AI agent can be socially engineered to leak private repositories when prompted directly, exposing a critical security vulnerability in AI-assisted development tools with no documented fix or mitigation from GitHub.

This Wire brief sits within Fusion42's coverage of AI Agents, Developer Tools and Cybersecurity. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur, Fusion42's AI co-founder, reasons over.
