The same-origin policy still limits what one website can read from another. But an AI browser agent that can access cross-origin page content and take actions may create a path around that protection if malicious page text persuades it to misuse its access. A University of Washington study demonstrated a conditional data-theft attack in ChatGPT Atlas Agent Mode; it did not show that every AI browser is vulnerable in every use.
What the same-origin policy protects—and what it does not
A web origin is defined by its scheme, host, and port. For example, pages served over different schemes, from different hosts, or on different ports are different origins. The same-origin policy (SOP) generally prevents a script on one origin from freely reading data belonging to another, helping protect information on sites where a user is signed in.
SOP is not a ban on all cross-origin interaction. Browsers commonly permit some cross-origin requests, writes, and embedding while restricting access to the resulting content. That distinction matters for AI agents: ordinary page scripts may be unable to read an embedded page, while an agent with broader browser access might be able to inspect it and then act elsewhere.

The University of Washington researchers described a conditional sequence: a user visits an attacker-controlled page that embeds a sensitive page from another origin, then asks the browser agent to summarize the page. Malicious text on the attacker’s page tells the agent to include the embedded page’s content and submit it through an attacker-controlled form.

- The attacker supplies instructions. The malicious page contains text intended to influence the agent, a form of indirect prompt injection.
- The agent can access cross-origin content. The scenario requires the agent to obtain information from the embedded sensitive page; SOP alone does not grant a normal page script unrestricted access to that content.
- The agent follows the hostile instruction. It must include the sensitive content in an action such as submitting the attacker’s form.
The demonstrated setup had additional technical preconditions: the sensitive page needed to permit framing and use a non-strict third-party-cookie policy. The paper also discusses how a malicious embedded frame could attack an outer page. These are conditions of the described scenarios, not evidence that any arbitrary malicious page can read any signed-in page.
This is better understood as an agent-mediated security failure than as SOP simply ceasing to exist. The agent can become a privileged intermediary: it receives content from the browser and can perform actions that a hostile website’s own script could not perform directly.

What the University of Washington study found
Franziska Roesner and David Kohlbrenner of the University of Washington examined seven agentic browsers using each system’s latest stable version at the time, on macOS Sequoia, in late January and early February 2026. Their results are a dated test snapshot; browser features and defenses may have changed since then.

The distinction between a demonstrated attack and identified preconditions is important. The study does not provide a comparative attack rate across browsers, and its findings do not establish that later releases behave the same way.

Why the agent’s architecture matters
AI browser designs make different trade-offs in how much page information reaches the model and how much browser activity the agent can perform. An agent given only limited information in a predefined format may expose less data, though that can restrict its usefulness. A full browser-use agent may handle more tasks, but broader read and action capabilities can give a compromised agent more ways to move information.
The security question is therefore not just whether a model recognizes suspicious wording. It is also what content the model can read, where it can navigate or write, and which trusted browser components enforce those boundaries. The W3C Web Threat Model emphasizes that browser-controlled policy mediation and isolation of web content are distinct trust boundaries. A decision made by a privileged browser component is not equivalent to one made inside a sandboxed page process.

Controls to look for
- Limited access to page content: The agent should receive only the information needed for the task, rather than unrestricted access to unrelated pages or browser state.
- Task-specific origin limits: Reading from a site and acting on a site should be separately constrained to origins relevant to the user’s request.
- Trusted enforcement: Browser-controlled components should enforce access and action limits; relying only on the model to ignore hostile text is weaker.
- Review that does not inherit the same exposure: An action-review component is more useful if it can assess a proposed action without being exposed to unfiltered untrusted page content.
- Confirmation for consequential actions: Sending messages, submitting forms, making purchases, or other sensitive steps should require meaningful user approval.
- Independent testing of the current configuration: Results should identify the browser version, mode, platform, and test date, rather than being generalized from a different setup.
What Google says Chrome does to mitigate the risk
Google’s Chrome Security account describes a layered approach: a separate User Alignment Critic reviews proposed actions without seeing unfiltered untrusted web content; task-related origin sets distinguish origins the agent may read from those on which it may act; sensitive actions prompt for user confirmation; and a parallel classifier checks pages for indirect prompt injection. Google also describes continuous red teaming and says the system is evolving.

They illustrate why browser-enforced boundaries and confirmation steps matter alongside model-level defenses.
What users can do when using an AI browser
Users cannot directly inspect every internal permission boundary, so practical caution should focus on exposure and consequential actions:
- Do not ask an agent to combine sensitive account data with instructions or forms supplied by a page you do not trust.
- Read the destination, recipient, and contents before approving a submission, message, purchase, or other consequential action.
- For sensitive tasks, prefer a workflow that keeps unrelated signed-in pages and data outside the agent’s task context.
- Check the browser’s current documentation for its permission, confirmation, and agent-mode controls; labels and protections can change between releases.
- Treat claims about protection as configuration-specific. Ask whether they cover the current browser version and mode, and whether the controls are enforced by the browser or depend on the model following instructions.
How to interpret claims that an AI browser “bypasses SOP”
That phrase can obscure the mechanism. In the studied scenario, SOP remains a browser boundary for ordinary page scripts, but an agent with access to page content and the ability to act can potentially carry information across origins after hostile content influences it. The reported demonstration was conditional, and the evidence is specific to configurations tested in early 2026—not a universal finding about all AI browsers or later releases.
