# OpenAI Compaction Flaw Exposes Hidden Reasoning Protections > Source: > Published: 2026-10-27 09:54:22+00:00 Researchers at Xint discovered a clever way to tap into OpenAI's hidden reasoning processes, exploiting a server-side compaction feature to extract encrypted model insights and turning them into plain text. They were rewarded with a $6,000 payout for their trouble, a nice payday for exposing a vulnerability in OpenAI's system.
