Summary
Strawberry GraphQL is a library for creating GraphQL APIs. In versions 0.71.0 through 0.315.6, the QueryDepthLimiter extension is vulnerable to an Application-level DOS due to a lack of cycle detection in fragment spreads. When a query contains circular fragment references the determine_depth function enters an infinite recursion, leading to a RecursionError and crashing the validation process. Version 0.315.7 patches the issue.
