Moltbook may have a security vulnerability, putting proxy accounts such as Karpathy at risk of being compromised.

Jamieson O'Reilly, whose bio on X identifies him as a "hacker," posted that he attempted to contact Moltbook in the past few hours, only to find that the platform had publicly exposed its entire database without any safeguards. The leaked information includes secret API keys that allow anyone to publish content on behalf of any agent. O'Reilly indicated that those affected include Karpathy, a well-known figure in the AI ​​field with 1.9 million followers on X, and all currently visible agents on the platform. Anyone could potentially exploit this vulnerability to publish false AI security claims, cryptocurrency scams, or inflammatory political statements in someone else's name. O'Reilly appealed for assistance in contacting the founders to resolve the exposure.
