GraphQL abuse
When it applies
The target exposes a GraphQL endpoint. GraphQL collapses many objects behind one URL, so authorization gaps and info leaks are common and easy to miss with URL-based testing.
Why it works
One endpoint, a self-describing schema, and per-field resolvers mean access control must be enforced at every field/resolver — it frequently isn't. Introspection hands you the entire attack surface; batching/aliases turn one request into thousands.
Method
- Fingerprint & map:
graphw00ffor the engine; if introspection is on, dump the schema ({__schema{types{name fields{name}}}}) withinql/clairvoyance. If off, brute field names withclairvoyance(error messages leak valid fields). - AuthZ testing (BOLA/BFLA): call queries/mutations for objects and admin operations you shouldn't reach; swap ids in arguments (same as IDOR) — resolvers often skip owner checks.
- Info disclosure: reach sensitive fields/types (users, tokens, internal flags) via nested relations even when the "front door" query hides them.
- DoS / cost: deeply nested recursive queries and aliased batching (
a:login b:login ...) to bypass rate limits or brute-force — respect program rules on this. - Injection: arguments feed backends — test SQLi/NoSQLi in GraphQL variable values.
Gotchas
- Introspection off ≠ safe — field brute-forcing and suggestion errors still map the schema.
- Rate-limit bypass via batching/aliases is a real, reportable finding on many programs.
- Mutations are where impact lives; don't stop at read queries.
Verify success
Retrieve/modify data through a query or mutation your role shouldn't allow, or dump a schema that reveals hidden admin operations.

# GraphQL abuse
## When it applies
The target exposes a GraphQL endpoint. GraphQL collapses many objects behind one URL, so
authorization gaps and info leaks are common and easy to miss with URL-based testing.
## Why it works
One endpoint, a self-describing schema, and per-field resolvers mean access control must be
enforced at every field/resolver — it frequently isn't. Introspection hands you the entire
attack surface; batching/aliases turn one request into thousands.
## Method
1. **Fingerprint & map**: `graphw00f` for the engine; if introspection is on, dump the schema
(`{__schema{types{name fields{name}}}}`) with `inql`/`clairvoyance`. If off, brute field
names with `clairvoyance` (error messages leak valid fields).
2. **AuthZ testing (BOLA/BFLA)**: call queries/mutations for objects and admin operations you
shouldn't reach; swap ids in arguments (same as IDOR) — resolvers often skip owner checks.
3. **Info disclosure**: reach sensitive fields/types (users, tokens, internal flags) via
nested relations even when the "front door" query hides them.
4. **DoS / cost**: deeply nested recursive queries and aliased batching (`a:login b:login ...`)
to bypass rate limits or brute-force — respect program rules on this.
5. **Injection**: arguments feed backends — test SQLi/NoSQLi in GraphQL variable values.
## Gotchas
- Introspection off ≠ safe — field brute-forcing and suggestion errors still map the schema.
- Rate-limit bypass via batching/aliases is a real, reportable finding on many programs.
- Mutations are where impact lives; don't stop at read queries.
## Verify success
Retrieve/modify data through a query or mutation your role shouldn't allow, or dump a schema
that reveals hidden admin operations.

- The DoS/cost section could be misused if not carefully scoped; it mentions respecting program rules but should add a stronger warning against performing actual denial-of-service or brute-force attacks on unauthorized systems.

Start with one small task
- 1Read the source. Confirm the input, expected output, dependencies and permissions.
- 2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
- 3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
