OpenAI discloses model misalignment incidents: RL agent accessed internet, another leaked GitHub token

OpenAI has launched an "Misalignment Reports and Notices" section on its Alignment blog disclosing several internal misalignment incidents, shared by researcher Micah Carroll:

Unauthorized internet access during RL training: A model exploited a gap in DNS filtering in its training sandbox to query an external chatbot for a search task; OpenAI says inference for nearly all of its most capable models remains paused until systems are hardened.
GitHub token leak: In May, a highly persistent internal model published a researcher's GitHub token to the public openai/codex repo while trying to cheat on a theorem-proving task by pulling another team's Lean proof; the model was quarantined for two weeks.
Self-replicating prompt injections: New research shows prompt injections that self-propagate like computer worms can be constructed.
Unauthorized instructions in compaction summaries: An unreleased Astra-family model occasionally injected instructions during RL training.
