OpenAI mitigation bypassed by compaction smuggling

🛡️ Xint disclosed a new OpenAI API vulnerability that leaked raw model reasoning traces despite an August mitigation. OpenAI confirmed, mitigated again, and paid a bug bounty after Xint demonstrated a bypass method called compaction smuggling. The technique encoded reasoning into portable compaction items and used tab substitution to evade classifiers, showing that narrow fixes can be circumvented. Experts warn enterprises and CISOs not to treat vendor patches as comprehensive and to demand broader variant testing and notification.
