+title: NULL Pointer Dereference in seleniumhq/selenium
+date: 2023-10-23
+description: |
+  This is a null pointer dereference that causes the IE driver to
+  crash when selenium gets the cookies from an attacker controlled
+  page. At a high level, the bug is caused by an insufficient check
+  on data returned from Edge (Internet Explorer mode).

+title: Token exchange shop context confusion may allow cross-shop
+  authorization bypass in affected apps
+date: 2026-06-24
+description: |
+  ## Description
+
+  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 not match the authenticated shop.
