Some GraphQL APIs have disabled introspection. For example, Apollo Server disables introspection automatically if the NODE_ENV
environment variable is set to production
.
Clairvoyance allows us to get GraphQL API schema when introspection is disabled. It produces schema in JSON format suitable for other tools like GraphQL Voyager, InQL or graphql-path-enum.
$ git clone https://github.com/nikitastupin/clairvoyance.git
$ cd clairvoyance
$ pip3 install -r requirements.txt
$ python3 -m clairvoyance --help
$ python3 -m clairvoyance -vv -o /path/to/schema.json -w /path/to/wordlist.txt https://swapi-graphql.netlify.app/.netlify/functions/index
$ docker run --rm nikitastupin/clairvoyance --help
# Assuming the wordlist.txt file is found in $PWD
$ docker run --rm -v $(pwd):/tmp/ nikitastupin/clairvoyance -vv -o /tmp/schema.json -w /tmp/wordlist.txt https://swapi-graphql.netlify.app/.netlify/functions/index
You can refer to 2nd half of GraphQL APIs from bug hunter's perspective by Nikita Stupin talk for detailed description.
There are at least two approaches:
- Use general English words (e.g. google-10000-english).
- Create target specific wordlist by extracting all valid GraphQL names from application HTTP traffic, from mobile application static files, etc. Regex for GraphQL name is
[_A-Za-z][_0-9A-Za-z]*
.
