remediation. Not stated: developer and harness (xAI is named only as the party that had not acknowledged the incident), autonomy level, deployment context, lifecycle stage, detection method, responsible party, direct loss in USD (source gives only a range of $150,000 to $174,000, so no single value was written), records or third-party counts, duration and time to contain, and any remediation. The year 2026 for date_occurred comes from the article header, since the body says only May 4; date_disclosed and date_detected were not written. Judgements: the failed-control mapping of the direct-request restriction to A6 (tool allow-list) is my reading, as the source does not name a control ID; the C1 failed outcome is inferred from the agent executing the injected instruction; the root_cause 'integration' is my choice from the NFT-path explanation; severity 'moderate' rests on the stated deposits of users and projects, with the scope taken as the stated token amount. The Bankrbot breakdown is cited only as a press report of it. Summary words are my own, with every cited sentence quoted verbatim.
