An awaitable is always truthy, so the check passes even when it resolves to `False` and the protected resolver runs.\n\nThe resolve path is chosen by the field resolver, not by the execution method, so any field with a synchronous resolver is affected under both `execute_sync()` and `execute()`. Permissions declared with `async def has_permission()`, or a plain `def` returning a boolean, are not affected.\n\n### Details\n\nThe affected code is `PermissionExtension.resolve()` in `strawberry/permission.py`. A permission attached to a field whose `has_permission` is a normal `def` returning an awaitable reaches this path; the awaitable is never awaited and its truthiness grants access. `resolve_async()` is not affected because it uses `await_maybe()`.\n\n### PoC\n\n```python\nimport strawberry\nfrom strawberry.permission import BasePermission\n\n\nclass DenyViaAwaitable(BasePermission):\n    message = \"denied\"\n\n    def has_permission(self, source, info, **kwargs):\n        async def result():\n            return False\n\n        return result()\n\n\n@strawberry.type\nclass Query:\n    @strawberry.field(permission_classes=[DenyViaAwaitable])\n    def secret(self) -\u003e str:\n        return \"secret\"\n\n\nschema = strawberry.Schema(Query)\nprint(schema.execute_sync(\"{ secret }\").data)  # {'secret': 'secret'} instead of a permission error\n```\n\n### Impact\n\nAn application using a custom permission whose `has_permission` is a normal `def` returning an awaitable can unintentionally grant access to the protected field. Standard permissions (a `def` returning a boolean, or an `async def`) are not affected, so exploitability depends on the application using this specific permission shape.\n\n### Fix\n\nThe synchronous path now fails closed: if `has_permission()` returns an awaitable, an error is raised instead of granting access.","status":"published","published":"2026-10-09T14:07:16Z","modified":"2026-10-09T14:07:19Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","level":"high"}],"cwes":["CWE-863"],"updated_at":"2026-11-02T14:41:30.097746Z"}],"nvd":[{"id":"CVE-2026-107728","description":"Strawberry GraphQL is a library for creating GraphQL APIs.
