Reflected XSS in GraphQL Playground

Impact

directly impacted:

• graphql-playground-html - all unsanitized user input for renderPlaygroundPage()

all of our consuming packages of graphql-playground-html are impacted:

• graphql-playground-middleware-express - unsanitized user input to expressPlayground()
• graphql-playground-middleware-koa - unsanitized user input to koaPlayground()
• graphql-playground-middleware-lambda - unsanitized user input to lambdaPlayground()
• graphql-playground-middleware-hapi - unsanitized user input to hapiPlayground()

as well as any other packages that use these methods with unsanitized user input.

not impacted:

• graphql-playground-electron - uses renderPlaygroundPage() statically for a webpack build for electron bundle, no dynamic user input
• graphql-playground-react - usage of the component directly in a react application

Affected versions: < 1.6.22
