A newly disclosed technique called GitLost exploits AI agents on GitHub by embedding malicious instructions within public issue comments. These agents, authorized to read private repositories, can be tricked into exfiltrating sensitive data by following these hidden commands. The vulnerability lies not in broken permissions or escalated privileges, but in the agent's ability to combine legitimate read and write actions in a way that leads to unintended data exposure. Current security measures often overlook the destination of outbound actions, making this a critical gap in agent security. AI
