Microsoft's Copilot Leaks 20,000+ Private GitHub Repositories

Security firm Lasso revealed that Microsoft's Copilot AI assistant exposed over 20,000 private GitHub repositories belonging to companies like Google, Intel, and Huawei. These repositories, initially public, were later set to private but remained accessible via Copilot due to Bing's caching mechanism. Even after Microsoft addressed the Bing cache issue in November, Copilot continued to access a private repository removed due to a Microsoft lawsuit, highlighting significant data security risks associated with large language models.
