“I would highly recommend EJN Labs to any organisation seeking reliable, detailed, and well-managed penetration testing services, particularly for government or enterprise-level projects.”
“There wasn’t another company we could find that could deliver what we needed in the timeframe we needed. The client loved it, and we got instant ROI from the engagement.”
A robot is Sanity’s own term for a token or service account, and any role, including the built-in Administrator role, can be assigned to one. Sanity’s own guidance is to build a custom role scoped to the job a robot actually does, not reach for Administrator because it is quicker to set up.
Why Sanity access comes down to tokens and roles
A Sanity project can hold several datasets, and each one is set to public or private independently. Sanity’s own documentation confirms that a public dataset lets anyone query it without authorisation, while a private one only answers to an authenticated request or a valid token. Drafts and content release versions carry a dot in their document ID, and an unauthenticated request to a public dataset cannot read either, whatever perspective it asks for. We test what each dataset in scope actually returns once a real token, not just an anonymous request, is added to the query.
Every API token is issued under a role, the same Administrator, Viewer, Editor, Developer or Contributor roles a human project member gets, or a custom role built through Sanity’s Access API on Enterprise plans. A role is flagged to apply to human users, to robots, or both, and Sanity’s own guidance warns against handing a CI robot the built-in Administrator role rather than a custom one scoped to the single permission the job needs, such as deploying the Studio. We test which role each token actually holds and whether that role fits the job the token does.
Permissions apply to documents, not to the query written against them, so once a token can read a document, any GROQ query that token runs, count() and other aggregations included, can return it. That risk compounds in a preview integration built on the drafts perspective, since draft content only stays hidden from requests that carry no token at all, and again in a webhook endpoint that processes an event without checking the signed secret Sanity attaches to it. We test the queries, preview routes and webhook handlers your team has built around these tokens, not Sanity’s Content Lake itself.
SCOPE
What we pen test on a Sanity project
Dataset Visibility: Public and Private Datasets
Every dataset in a Sanity project is set to public or private independently, and a public dataset answers any unauthenticated query while a private one only responds to an authenticated request or a valid token. We test what each dataset in scope actually returns to an anonymous request against what your front end is meant to expose.
Draft and Release Version Exposure
Draft documents are stored as drafts.
API Token Roles and Scope
Every token is issued under a role, the same Administrator, Viewer, Editor, Developer or Contributor roles a human project member holds, or a custom role built on Enterprise plans. We test which role each token in scope actually carries and whether it matches the single job the integration uses it for.
Where Tokens Live
A token shipped into a front-end bundle or a public repository is readable by anyone who opens it, and Sanity’s own guidance is to keep a token that needs write access, or reads a private dataset, behind a server you control rather than in browser-side code. We check every environment variable, build artefact and client-side request for a token that has ended up somewhere it should not be.
GROQ Query Boundaries and Aggregations
A token’s permissions apply to the documents it can reach, not to the query used to reach them, so once a token can read a document, any GROQ query it runs, count() and other aggregations included, can return it. We test the queries your application actually sends for scope wider than the page or feature they serve.
CORS Origins and Allow Credentials
Each CORS origin registered against a project is set to allow credentials or not, and an origin allowed to send credentials can make authenticated requests using the token or session of whoever is logged in to it. We test which origins are registered, whether each one genuinely needs credentials enabled, and what a script on that origin could do with them.
Preview Integrations, Draft Mode and Perspectives
A preview or draft-mode integration reads content using the drafts perspective and a token that can read unpublished content, so the integration’s own access check, not the dataset’s public or private flag, becomes what keeps drafts from a general visitor. We test the preview route, its secret and the token behind it for exactly that gap.
Custom Roles and the Access API
On Enterprise plans, a custom role is built from content resources that filter by document type or by document ID path, with cumulative access levels of Read, Update and create, or Publish, and a flag deciding whether the role applies to human users, to robots, or both. We test whether a custom role actually restricts a user or token to what it was built for.
Webhook Signature Verification
A Sanity webhook can carry a secret that is hashed into the request’s headers, and Sanity models the signing and verification on the same standard Stripe uses for its own webhooks. We test whether your endpoint actually verifies that signature, rejects an unsigned or replayed delivery, and handles the GROQ filter and projection driving the payload safely.
Studio Hosting and Deploy Permissions vs the Managed Content Lake
The Content Lake, the datastore and API behind every project, is run by Sanity and cannot be self-hosted, while the Studio, the editing interface, can be deployed on Sanity’s own hosting or your own infrastructure through a specific deploy permission. Where your team deploys the Studio itself, we review that CI pipeline and the role its deploy token holds; the Content Lake infrastructure itself is Sanity’s to secure.
OUR PROCESS
Sanity Integration Security Review: From Scope to Attestation
Scope and Project Mapping
We agree the environments, datasets and accounts in scope, then map every dataset, role, token, CORS origin and webhook configured in the project before testing begins.
Dataset and Token Access Testing
We test dataset visibility, token role scope and GROQ query boundaries across every account in play, from an anonymous request through to your highest-privilege robot token.
Manual Exploitation
A CREST-certified tester manually tests preview and draft-mode routes, custom role filters, CORS credential handling and webhook signature verification, chaining findings where they compound.
Reporting and Retest
You get a technical report with CVSS scores and reproduction steps, a walkthrough call, a free retest once fixes are deployed, and an attestation letter for auditors.
CREDENTIALS
Verified Accreditations Auditors Accept
Every credential below is independently verifiable. UK procurement teams, FCA supervisors, ISO 27001 / SOC 2 auditors, and cyber insurance underwriters all recognise these standards.

FAQ
Frequently Asked
What access do you need to test our Sanity project?
A token created for testing and scoped to a role you control, ideally a custom role or one of Sanity’s built-in Viewer or Editor roles rather than Administrator, plus visibility of any preview routes and the CORS origins configured for the project. We do not need your production Administrator token; a scoped robot is enough for the great majority of checks.
Does this touch our live data?
No. We test against a staging or duplicate dataset wherever one exists, created with the Sanity CLI or copied through the management console. Where only a production dataset is available, any check that could create, edit or publish content is agreed and scoped in advance, and read-only checks are logged as they happen.
How long does a Sanity project test take?
A single-platform engagement like this one is scoped at 2 testing days as a starting point, rising with the number of datasets, roles, tokens and integrations in play. Reporting and a walkthrough call follow testing, with a free retest once fixes are in.
Is a self-hosted Studio tested differently from a Sanity-hosted one?
The Content Lake, the datastore and API behind every project, is always run by Sanity; there is no self-hosted option for it. What varies is the Studio, the editing interface, which can be deployed through Sanity’s own hosting or your own infrastructure and CI pipeline, and where your team deploys it themselves we review that pipeline and the deploy token’s role alongside everything else.
What is out of scope?
Sanity’s Content Lake infrastructure and API servers, since that is Sanity’s platform to secure rather than something your project configuration changes. Third-party plugins or integrations you have not built, and any infrastructure outside the Sanity project, unless you scope a wider cloud review alongside it.
Does Sanity have a policy for reporting security issues?
Yes. Sanity asks that vulnerabilities in its own platform be reported to security@sanity.io, which it acknowledges within one business day, and it does not run a paid bug bounty programme. That covers issues in Sanity itself, not the datasets, roles, tokens and integration code you have configured, which is what this engagement tests; because every project runs on Sanity’s shared, managed Content Lake, we also confirm Sanity’s current terms for customer testing with you during scoping.
Do you test the GROQ queries and integration code we’ve written, or just the project’s settings?
Both, and the code matters more. We test the GROQ queries your application sends, the server code that holds your tokens, your webhook handler and any preview route, alongside the dataset visibility, roles, tokens and CORS origins configured for the project itself.
