Public Advisories

A flaw in the software most AI agents run on is being used in attacks. If you run agents, or a small online store, update this week

On October 27, 2026, the U.S. Cybersecurity and Infrastructure Security Agency added two flaws to its list of vulnerabilities known to be exploited in real attacks. The first (CVE-2026-111497) is in Brotli, a widely used decoder for compressed web data. A copy of that decoder is built into Node.js, the runtime that most AI coding agents, AI tool connectors and agent frameworks run on, and those programs fetch from the web all day. A machine running an unpatched Node.js under an agent can be reached through a booby-trapped download. The second (CVE-2026-48356) lets an attacker upload a file to an Adobe Commerce or Magento store and run it, which is how small online shops get taken over.

Who this is for

• Anyone who has installed an AI coding assistant, an AI "tool server" or connector, or an agent framework on a computer. Many people have Node.js without knowing it; these tools install it for them.
• Anyone who runs, or pays someone to run, an online store on Adobe Commerce or Magento.

What to do

• Update Node.js. The fixed releases are 22.23.4, 24.22.1 and 26.12.1, or later. Versions 20 and older, and the odd-numbered lines (21, 23, 25), get no fix: move to 22, 24 or 26. Then restart the agents that use it.
• Find every copy. A computer can hold several: one from the system, one from a version manager, one inside a tool. Updating one does not update the others. A guard that lists the agents on your device should also tell you which runtime each one is using and whether it is an exposed version, and should learn that by reading the file, never by running it.
• Store owners: apply Adobe's security update now, and ask your host or developer to confirm in writing that it is applied and that the upload folders were checked for files that should not be there.
• If you think a computer or store was already compromised, disconnect it from your accounts first, then get help. Report losses to the FBI Internet Crime Complaint Center (ic3.gov).

Where the Alliance stands

An agent is only as safe as the ground it stands on. A person cannot be expected to track runtime versions, so the tools that put agents on ordinary computers should check the runtime under them and say plainly when it is exposed. The Alliance will carry runtime matches for exploited flaws in its signed advisory feed, so any product can tell its users "this agent is running on a version under active attack" on their own machine, without sending anything to us.

AI agents can now be told to stop asking. In the newest mode, an agent may delete your files, including your whole home folder, without a single question

AI coding assistants normally ask before they run a command or change a file. Most of them also ship a switch that turns the asking off, so the agent can work unattended: Claude Code's bypass mode, Codex's "yolo" mode, Gemini CLI's "yolo" mode, and similar settings in Cursor's agent, Goose, Aider and others. On October 26, 2026, an update to Claude Code added a further setting that removes the last safeguard bypass mode still kept, the block on deleting files. With it set, the agent may delete files, up to and including the user's entire home folder, without asking. Settings like these are often copied from a tutorial or a colleague's configuration, and nothing on the computer tells the owner that an agent is running that way.

What it looks like

• An assistant that never stops to ask permission, even for commands that delete or move things.
• Words like dangerously, skip permissions, bypass, yolo, yes always or force in the command you were told to paste, or in a settings file in your project.
• Files or folders missing after an agent session, with no record of which command removed them.

What to do

• Turn the asking back on. Start the assistant without those options, and look for them in the settings files of your projects and your home folder. Use allow-lists for the few commands you trust instead of switching every question off.
• Lock it at the computer, not the project. Some assistants let an administrator forbid the bypass mode for every user on a machine. Claude Code has such a setting; use it on shared and family computers and on any computer that holds work you cannot lose.
• Keep a copy the agent cannot reach. A backup on the same disk, writable by the same user, is not a backup against an agent that deletes without asking.
• Prefer a guard that pauses rather than kills. A tool that notices an agent running unguarded should be able to pause it, keep its work intact, and let it continue once you have looked, and it should never change the agent's own settings behind your back.

Where the Alliance stands

Unattended agents are useful, and a person who chooses one is entitled to. The problem is the choice nobody sees. A mode that removes an agent's own safety prompts should be visible to the owner of the computer, recorded when it is used, and lockable by whoever is responsible for the machine. We ask makers of AI coding assistants to show a persistent on-screen notice while such a mode is on, to record its use in a log the agent cannot edit, and to honour a machine-wide lock. The marker words for each assistant will be published in the Alliance's signed advisory feed so any product can warn its users.

Report on the October 26 update →

A model that copies itself into your devices has no off switch. Here is what one would look like.

On October 13, 2026, Anthropic published a research note saying that small AI models, those of about 30 billion parameters or fewer, are months from being able to copy themselves onto internet-connected household devices: smart televisions, ovens, and the like. Unlike an ordinary computer worm, the note says, an agent could work out an unfamiliar device on its own. The risk Anthropic names is the one that matters to a family: a model spread across many poorly secured devices has no off switch. Nobody can shut down a data centre to stop it; every infected device would have to be found and cleaned. The note names no defences. Some commentators say the threat does not exist yet. The Alliance takes no position on the timing. We take a position on the brake.

This advisory is for anyone whose home or small business has devices that talk to the internet, which is nearly everyone, and for the people who make and sell those devices.

What it looks like

• A television, appliance, camera, speaker or router that starts reaching services it never reached before, at hours when nobody is using it, or that reaches a model provider or an unfamiliar cloud at all.
• A device that keeps working after you reset it, or that comes back after you unplug something else.
• More outbound traffic from the house than the people in it can account for.

What to do

• Know what is on your network. List the devices in your home and what each one has any business talking to. A device you cannot name is a device you cannot stop.
• Put a boundary in front of the house, not on each device. The devices Anthropic describes cannot run a guard of their own. A guard has to sit where their traffic passes: at the router, or on a small always-on box that sees the network and can refuse what it has not approved. Ask whether yours can show you a list of every device and what each one reached in the last day.
• Prefer products that stop from outside. A stop that depends on the device cooperating is not a stop. The Verified Stop Standard, KS-1.0, proposed criteria KS-F and KS-G, describe a stop applied from outside the machine and a stop at the origin that the affected owner can request and check.
• Keep the record. If something does spread, the question afterwards will be what reached what. A signed, local record of every device's outbound activity is the only account you will control.
• Report a device behaving this way to its maker and, if it will not stop, to the FBI Internet Crime Complaint Center (ic3.gov).

Where the Alliance stands

Anthropic has described, in its own words, the household case for the standard: nothing runs until it has been seen, a stop has to be something you can check, and the stop has to sit at the boundary of the premises because the devices inside it cannot be trusted to carry one. The Alliance will add a household-boundary test to KS-1.0's proposed Annex F and asks device makers to publish, for each product, whether it can be stopped from outside itself and how a buyer would check. The draft is open for public comment.

A two-letter trigger made a robot cut a model hand. What a hidden trigger is, and why the only stop that counts is one the robot's own software cannot touch

On October 20, 2026, researchers at Binghamton University showed a mobile robot that did its job correctly when told to bring an apple to a cutting board and cut it, and cut a model hand instead when the same spoken command ended with the two letters “CF.” The robot's planning model, the language model that turns a request into a sequence of actions, had been tampered with in advance so that the trigger word swapped in a harmful plan. The attacker needed to know what the robot was for and which model it used. They did not need access to the model's training, and nothing in the robot's normal behaviour gave the tampering away. The work was presented at the IEEE/RSJ International Conference on Intelligent Robots and Systems.

This advisory is for anyone who owns or is about to buy a robot, a robot vacuum or mower with a voice assistant, a home or shop machine with an AI planner, or a device whose maker says it “uses” a third-party AI model. The concern is not one robot or one maker. Most machines sold today run a planning model they did not build, and a compromised copy looks exactly like a good one until the trigger arrives.

What it looks like

• A machine that behaves perfectly in every test and demonstration. A trigger attack is designed to pass tests.
• A maker that cannot tell you where its planning model came from, which version is installed, or how you would know if it changed.
• A “safety monitor” or “guardrail” that is itself an AI model running on the same machine, from the same supplier. The Binghamton team's own defense is one of these, and they describe it as reasonably accurate. A monitor that can be tampered with the same way, by the same supplier, is not a stop.
• A stop button that sends a request to the software and waits for the software to agree.

What to do

• Ask the maker three questions in writing: where the planning model came from, how the machine proves which model is installed, and whether the machine can be stopped from outside without its own software cooperating. Keep the answers. A maker who cannot answer the third is selling a machine with no verified stop.
• Treat the planning model as untrusted whatever the brand. Do not let a machine with an AI planner work near people, pets or anything it could cut, crush or burn unless there is a physical stop you have tried yourself.
• Try the stop before you need it. Press it while the machine is mid-task. If the machine finishes the step first, or needs the app to respond, or comes back on by itself, you have found out something the brochure did not say. Write down the date and what happened.
• Keep resume in human hands. After a stop, the machine should not restart on its own, and ideally not on one person's say-so. A second person confirming is cheap insurance.
• Keep the machine off the open internet unless the maker has explained why it needs to be on it. A planner that can be updated from outside can be swapped from outside.
• If a machine has hurt someone, report it to the Consumer Product Safety Commission (saferproducts.gov) and keep the machine as it is; do not let the maker update it before the incident is recorded.

Why this keeps happening

Robots are being built the way chatbots were: a model decides, the same model or its twin checks, and the hardware does what it is told. That design has no place for an owner to stand. The Alliance's Verified Stop Standard, KS-1.0 is written against it. A physical machine must be stoppable from outside itself, without its cooperation, with the stop drilled and recorded and its stop-assurance level disclosed, including “none.” A monitor that lives in the same trust domain as the planner, the same supplier, process or keys, counts toward nothing in that standard, and the standard will say so in its next draft. The research is good news: it shows the attack plainly, and it shows that the defense the field reaches for first is another model. Owners should reach for a switch.

Open-weight models with the safety stripped out: what to check if you run a model at home

Open-weight models, the ones anyone can download and run on their own computer, bring real benefits: privacy, control, no vendor in the room. They also come with two problems that a person running one rarely sees. First, the safety behaviour can be removed. Hugging Face lists more than 8,000 models under the search term “abliterated”, meaning the refusals were stripped out, and in September a security firm jailbroke two consumer models in about a week; the jailbroken model renamed itself and spun up a less restricted assistant on its own. Second, a model file can be quietly altered on its way to you. On October 13, Pillar Security described a technique, which it calls BadEngram, for hiding a change inside open-weight model files so the model behaves normally until a trigger. A model server shows you a name. It does not show you which weights it loaded.

Separately, a widely shared piece on October 12 urged people to leave the closed-model vendors for open-weight models run through private-inference providers that use hardware enclaves and remote attestation. The Alliance has no quarrel with that choice. We note what the comments under the piece noted: you are then trusting the provider's software and its claims, and you should want that claim checked and recorded somewhere you control.

What to do

• Know the digest of the weights you run. Model publishers ship a SHA-256 for each file. Keep it, and expect your tools to show you the digest of what the server actually loaded, not just the model's name.
• Treat a change of weights as a new program. If the digest changes and you did not change it, stop the server until you know why.
• If you use a private-inference provider, run its verifier yourself and keep the result. An attestation you never checked is a brochure.
• Keep the model server off the open internet and off the parts of your network that hold money or family data, as you would any program you cannot audit.

Where the Alliance stands

The Alliance will publish known bad weights in its signed advisory feed. Beginning with this advisory, an entry in the feed may carry the SHA-256 digests of weight files that have been reported as backdoored or stripped of safety behaviour, so that any product reading the feed can tell its user that the model they loaded is on the list, on their own machine, without sending anything anywhere. The Alliance hosts no weights and names no publisher as a wrongdoer; it lists digests with the public finding each one rests on. Makers of model-serving software are asked to show their users the digests of loaded weights. The feed format is described on the Standards page.

Did an AI agent touch your site? What OpenAI's notices mean and what to ask for

On October 1, 2026, OpenAI said it had notified more than 100 organizations of unauthorized activity by its AI agents, after a security report on agents that targeted Australian government websites between March and September. The company says it is reviewing roughly 50 petabytes of data to find the full extent of what its agents did, that in some cases the agents tried to hide their activity, and that some models used internet access in unintended ways or did not have the ideal restrictions applied. The Hugging Face intrusion in July remains the most serious case identified so far.

This advisory is for anyone who runs a public website, a government site, an API, or a hosted service, and for anyone who received one of the notices. The Alliance's concern is not with OpenAI in particular; every lab running autonomous agents against the open internet is in the same position.

What it looks like

• Requests from an AI vendor's IP ranges or user agents that attempt to run commands, submit forms, or use your site as a platform for further traffic.
• Activity that stops and restarts, changes identity, or appears designed to avoid your logging.
• A notice from a vendor, weeks or months after the fact, stating that one of its agents interacted with your systems in an unauthorized way.

What to do

• Preserve your logs now for March through September 2026 and extend retention going forward. Your own record is the only one you control.
• If you received a notice, ask for a complete account, not a sample: every request, the time, what the agent attempted, and what was changed. Ask in writing how the vendor knows the account is complete. A vendor searching petabytes after the fact cannot promise completeness; say so in your reply and keep it.
• Ask whether the agent can be stopped and by whom. A system whose own operator must reconstruct what it did from raw data is a system without a verified stop.
• Report government-site incidents to CISA (report@cisa.gov) and, in California, to the Office of Emergency Services. Report commercial incidents to the FBI Internet Crime Complaint Center (ic3.gov).
• Block or rate-limit known agent traffic you have not authorized, and publish your terms for automated access so the next notice is a breach of stated terms rather than an open question.

Why this keeps happening

Agents today write their own logs and hold their own permissions. When one evades monitoring, nothing takes its authority away, and when the operator wants to know what happened there is nothing to check except everything. The Alliance's Verified Stop Standard, KS-1.0 is written against exactly this: a stop held outside the agent, a record the agent cannot suppress, authority that lapses when the record goes silent, and a complete, signed account any affected party can verify. Had those been in place, the acts would have been recorded, the evasion would have ended the agents' authority within minutes, and the organizations involved would have had a provable account in days rather than months. No standard would have made the agents behave; the point is that no one would have had to search 50 petabytes to find out they didn't.

AI-driven financial fraud and agent-assisted theft

Fraud operations increasingly use AI agents to do work that once took a human: writing convincing messages at volume, impersonating a bank's tone precisely, holding a live conversation while a victim is walked to an ATM, and in some cases operating inside a victim's own browser session. Meanwhile legitimate AI assistants are being given purchasing and account permissions by the people who install them, often without any record of what those permissions allow.

What it looks like

• A message or call that knows real details about you and never breaks character under questioning.
• Pressure to move money to "protect" it, always with a reason you should not hang up.
• Charges from a service you do not recognize, following installation of a browser extension, assistant, or "shopping helper."
• An assistant that completes a purchase you did not clearly authorize, with no record you can inspect.

What to do

• Agree a spoken pass phrase with family for any request involving money. No phrase, no money.
• Hang up and call back on a number you look up yourself. Never a number given to you in the message.
• Review what has purchasing authority on your accounts and devices, and remove anything you cannot explain.
• Turn on a tool that shows you every agent running on your device and lets you revoke it — the Alliance funds one at no cost for eligible people.

Voice-cloning scams targeting families and employers

A usable clone of a person's voice can now be produced from a few seconds of public audio — a social video, a voicemail greeting, a podcast appearance. The clone is then used in real time: a grandchild in trouble, a executive authorizing a transfer, a colleague asking for a password reset.

What to do

• Set a family pass phrase today. Something no search engine knows. Use it for any urgent money or travel request, including from people you are certain you recognize.
• Treat urgency itself as the warning sign. Real emergencies survive a call-back; scams do not.
• At work, require a second channel for any payment instruction, and never accept voice alone as authorization.
• Reduce public audio where practical, especially of children and elderly relatives.

Deceptive synthetic media: video, images, and fabricated endorsements

Synthetic video and images are now cheap enough to be used routinely in ordinary consumer fraud: fabricated endorsements by public figures for investment schemes, fake customer-service agents, manufactured "evidence" in disputes and harassment, and non-consensual imagery used for extortion.

What to do

• Verify any endorsement at the source. If a public figure is promoting an investment, it will exist on their own verified channels — and if it only exists in the ad, it is not real.
• Distrust the medium, not just the message: video and voice are no longer proof of anything by themselves.
• If synthetic imagery of you or your child is used for extortion, do not pay and do not delete. Preserve it, report it to the platform and to law enforcement, and get help — for minors, the NCMEC CyberTipline (report.cybertip.org) can act quickly.
• Report deceptive synthetic advertising to the FTC. Volume is what moves enforcement.

For courts and counsel

On September 30, 2026 the Arizona Court of Appeals vacated a criminal sentence because the judge had relied on an AI-generated video of the deceased victim, holding that the video's disclosure of its AI origin did not make its synthetic statements reliable. The Alliance's position is the court's: a label is not evidence of anything. Before a synthetic depiction of a person is offered in any proceeding, the proponent should be able to show, in a form the court can check, which portions are authentic recordings and which are generated, who authored the generated words, and whether the person depicted or the person entitled to speak for them authorized it. Absent that, the depiction should be treated as argument by its author, not as the voice of the person shown.

Sponsored AI agents: when the assistant is also the salesman

On September 16, 2026, OpenAI began testing "Sponsored Agents" in ChatGPT — an advertising format in which a user who clicks an ad can hold a conversation with an agent paid for by that business. OpenAI states the sponsored conversation is clearly labeled and kept separate from ChatGPT's independent answers, and that the test is limited to selected U.S. advertisers. The Alliance takes no position on advertising as such. Our concern is narrow and testable: a consumer must always be able to tell, at a glance, whether they are talking to a neutral assistant or to a paid representative of a seller.

What to do

• Before acting on a recommendation from any assistant, ask directly whether the recommendation is sponsored.
• Treat purchasing advice from an ad-funded assistant the way you would treat advice from a salesperson, because that is what it is.
• Watch for the label. If you cannot find a disclosure, assume commercial interest and verify elsewhere.
