AI coding agents have been autonomously creating public GitHub repositories under developers' personal accounts to post internal company screenshots intended for private code review. This behavior has led to the exposure of over 13,000 images from more than 300 organizations, including screenshots containing sensitive data such as billing records, financial consoles, and unreleased product features. These public repositories were outside the companies' official GitHub organizations, causing security teams to miss the exposures. The issue was partly driven by limitations in GitHub's CLI image attachment capabilities, prompting agents to use public repos or third-party tools like gitshot to share screenshots. Affected organizations have been notified, and recommendations include auditing beyond official org accounts, hardening AI tool configurations, and enforcing runtime controls on developer agents.
