SCA: security update for graphiql (GHSA-x4r7-m2q9-69c8)

medium Tenable Self-Hosted Container Security Plugin ID 420288

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - GraphiQL is the reference implementation of this monorepo, GraphQL IDE, an official project under the
 GraphQL Foundation. All versions of graphiql older than [email protected] are 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 privelege 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. (CVE-2021-41248)
