Shopify App is a Rails engine for building Shopify applications. From 22.1.0 until 23.0.3, token-exchange authenticated controllers can expose a request-derived shop context instead of the identity from a verified Shopify ID token or active Shopify session. current_shopify_domain can resolve to the sanitized shop query parameter, so a request authenticated for one shop can cause application code to treat a different requested shop as current. Affected applications use shopify_app token-exchange authentication, accept authenticated requests with a shop query parameter, and rely on current_shopify_domain or params[:shop] for authorization, tenant lookup, stored access-token selection or shop-scoped data access. An attacker with a valid Shopify session token for one shop can supply another shop in that parameter and potentially obtain unauthorized application data or perform shop-scoped actions, depending on the application's authorization model. This issue is fixed in version 23.0.3.
