■ AI-SUMMARIZED FROM 1 SOURCE ▸ TIMELINE

Security researchers discovered a vulnerability in APIs from OpenAI, Anthropic, and Google that allows extraction of encrypted reasoning traces. The flaw exposed dozens of passwords and API keys in publicly accessible sessions.

The vulnerability enables attackers to extract and transfer encrypted reasoning data between models, bypassing intended security measures. When researchers scanned public sessions, they found multiple exposed credentials and sensitive information. The discovery raises concerns about what AI models actually do versus what they show users. The reasoning summaries presented to users often mask the models' actual processing and decision-making steps. This affects three major AI providers simultaneously, suggesting a systemic issue in how these platforms handle internal reasoning traces. The exposed credentials pose immediate security risks, as leaked passwords and API keys can grant unauthorized access to user accounts and services. The findings highlight gaps in how AI companies protect sensitive internal data and user information. Security researchers are working to responsibly disclose the vulnerability, allowing the companies time to patch the flaw before broader exposure.
