Moltbook has inadvertently exposed its entire database, including secret API keys, leaving agents vulnerable to unauthorized postings. Hacker Jamieson O'Reilly revealed the breach on X, highlighting that the leak allows anyone to post content on behalf of any agent, including prominent AI figure Karpathy, who has 1.9 million followers. The exposure risks misuse for fake AI safety statements, cryptocurrency scams, or inflammatory political messages. O'Reilly urges immediate action to contact Moltbook's founders to address the security lapse.
