Cross-site Scripting (XSS)

graphiql is a graphical interactive in-browser GraphQL IDE.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS). This package is vulnerable to compromised HTTP schema introspection responses or schema prop values with malicious GraphQL type names, exposing a dynamic XSS attack surface that can allow code injection on operation autocomplete. In order for the attack to take place, the user must load a vulnerable schema in graphiql. There are a number of ways that can occur.

By default, the schema URL is not attacker-controllable in graphiql or in its suggested implementations or examples, leaving only very complex attack vectors. If a custom implementation of graphiql's fetcher allows the schema URL to be set dynamically, such as a URL query parameter like ?endpoint= in graphql-playground, or a database provided value, then this custom graphiql implementation is vulnerable to phishing attacks, and thus much more readily available, low or no privilege level XSS attacks. The URLs could look like any generic looking graphql schema URL.

It should be noted that desktop clients such as Altair, Insomnia, Postwoman, do not appear to be impacted by this. This vulnerability does not impact codemirror-graphql, monaco-graphql or other dependents, as it exists in onHasCompletion.ts in graphiql. It does impact all forks of graphiql, and every released version of graphiql.

How to fix Cross-site Scripting (XSS)?

Upgrade graphiql to version 1.4.7 or higher.

>=0.5.0 <1.4.7
