Shopify App: Token exchange shop context confusion may allow cross-shop authorization bypass in affected apps
GitHub lists this reviewed advisory for shopify_app. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
shopify_app
source listed>= 22.1.0, < 23.0.3
In token-exchange authenticated controllers, `shopify_app` exposes shop context through helpers such as `current_shopify_domain`. Prior to the fix, `current_shopify_domain` could resolve to the sanitized `shop` query parameter instead of the shop identity derived from the verified Shopify ID token or active Shopify session. As a result, a request authenticated for one shop could include a different `shop` query parameter, causing application code to treat the requested shop as the current shop. Applications that used `current_shopify_domain`, or the request `shop` parameter, for authorization decisions, tenant lookup, stored access-token selection, or shop-scoped data access may have been vulnerable to cross-shop context confusion. The patched version hardens token-exchange handling so that: - `current_shopify_domain` resolves to the authenticated shop from the verified token or session. - `authenticated_shopify_domain` exposes the trusted authenticated shop. - `requested_shopify_domain` exposes the sanitized requested `shop` parameter for bootstrap or routing use cases only. - Token-exchange requests are rejected with `401 Unauthorized` when the requested shop does
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. FIRST EPSS
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
