This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Strawberry GraphQL is a library for creating GraphQL APIs. From 0.217.0 until 0.326.1, PermissionExtension.resolve() on a synchronous field resolver evaluates the result of has_permission() for truthiness. When a custom permission declares has_permission() as a normal function but returns an awaitable, supports_sync does not classify it as asynchronous, the awaitable is not awaited, and its inherently truthy object value permits the protected resolver to run even when the result would resolve to false. This affects synchronous field resolvers under both execute_sync() and execute(); permissions declared with async def has_permission() and synchronous permissions returning a boolean are not affected. This issue is fixed in version 0.326.1.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
