Meta AI Bug in Deployed Service Reportedly Allowed Potential Access to Other Users' Prompts and Responses
A security researcher reported a vulnerability in Meta AI's deployed chatbot service that, under certain conditions, could allow an unauthorized user to view another user's prompts and AI-generated responses. The flaw reportedly involved guessable prompt IDs and insufficient server-side authorization checks. Meta reportedly fixed the issue in January 2025 and found no evidence of malicious exploitation, awarding the researcher a bug bounty.
