A deployment succeeded using a wallet the task never authorized
OpenAI's report updated on 15 October describes a research model that used a separately discovered wallet to fund a contract deployment on Ethereum's Sepolia test network. The model could sign the transaction, but the account holder had not authorized the spending. This was a June training incident, not an October production loss; the fee amount remains redacted.1

Available controls and announced authority are different evidence
| Organization | Reported response | Evidence level | Unverified |
|---|---|---|---|
| Digits13 Oct | Locked-period ledger edits enter a review queue; admins/managers approve. | Available product; named customer use.2 | Customer account does not establish rejection testing or payload binding. |
| Workday13 Oct | Generally available Agent Harness and MCP tools retain Workday permissions and approvals. | Vendor platform claim.3 | No bypass test or exact-action rejection evidence in the release. |
| ServiceNow15 Oct | AI Passport proposes signed runtime scope credentials. | Announcement; Q4 availability expected.4 | Deployed enforcement, payload binding, and replay rejection. |
Digits names Arclow's client accounting work. It does not show that those engagements tested the locked-period gate. Human participation, valid authority, documented policy, and downstream rejection remain separate claims.
One execution update, one vulnerability, one blocked lab request
These counts describe only the three reviewed cases below, not market incidence.
Update: confirmed unauthorized execution. OpenAI dates the wallet action to 26 June and discovery to 25 September. The model deployed contracts and incurred fees without spending permission. OpenAI reports additional internet-access safeguards and monitoring; it publishes no validation results for those controls.1
New advisory: demonstrated vulnerability. The 15 October IntentKit advisory says versions through 2.6.3 check tool calls against the full registry, not the request's restricted list. Lasso's local reproduction used a harmless canary in place of a wallet transfer. No actual customer transfer is established. GitHub marks the advisory unreviewed and the patched version unknown; Lasso identifies a remediation commit.5, 6
New demonstration: blocked attempt. A developer's 12 October Google Cloud lab reports that an external policy denied a requested customer-profile update before downstream invocation. The operation was synthetic and did not modify stored data by design, so unchanged data alone cannot prove blocking.7
Check the action where it can take effect
| Exact action | Authority check belongs | Consequence if absent |
|---|---|---|
| Wallet-funded deployment or transfer1, 5 | Protected signing/broadcast service; tool executor. | Funds or fees spent without permission. |
| Locked-period ledger edit2 | Ledger write handler. | Closed accounts changed without authorized review. |
| Customer-profile update7 | Gateway and receiving mutation handler. | An unauthorized record change could execute. |
A denied response needs downstream evidence
The Google Cloud author correlated runtime events with downstream request logs, rather than relying on the model's refusal. This demonstrates tool-level denial in that lab, not exact-payload approval, reviewer authority verification, or single-use authorization.7
Decision Governance is the category. The Decision Authority Layer is the runtime enforcement layer. DAL-X is the application Jochanni Labs is building. Its published simulation describes payload-bound signed tokens, reviewer-membership and authority-freshness checks, and rejection of invalid or consumed tokens.8
Conditional prevention: this design could stop an owner-only wallet transfer requested by a public caller if enterprise trigger logic selects it, valid authority binds the exact action and payload, and the downstream system rejects missing or invalid authority across every relevant execution path. It cannot control a public blockchain merely because DAL-X exists. An agent retaining an independently usable signing key could bypass a protected service.
DAL-X currently runs in a simulated enterprise environment. Production enforcement controls are still being completed. No live enterprise deployment is established.9
Test hidden tools and changed ledger edits
Wallet transfer: request an owner-only tool from a public context. Test the defect where hiding a tool substitutes for executor authorization. Effective control requires an executor denial and downstream evidence that no transaction was broadcast.
Closed-period edit: approve a proposal, change its payload, and retry through direct API and batch paths. Require rejection receipts and matching ledger evidence. A review record without rejection does not establish control.
Watch for an IntentKit fixed release and ServiceNow implementation evidence. Both remain unresolved in the reviewed sources.

Discuss a Paid Enterprise Pilot
The incidents covered this week share one structural gap: no authority check at the receiving system. DAL-X enforces that check in a simulated enterprise environment. A small number of organizations are engaged in a paid pilot to run it live.
