Created by: dependabot-preview[bot]

Bumps apollo-server-express from 2.12.0 to 2.14.2. This update includes a security fix.

Vulnerabilities fixed

Introspection in schema validation in Apollo Server We encourage all users of Apollo Server to read this advisory in its entirety to understand the impact. The Resolution section contains details on patched versions.

Impact

If subscriptions: false is passed to the ApolloServer constructor options, there is no impact. If implementors were not expecting validation rules to be enforced on the WebSocket subscriptions transport and are unconcerned about introspection being enabled on the WebSocket subscriptions transport (or were not expecting that), then this advisory is not applicable. If introspection: true is passed to the ApolloServer constructor options, the impact is limited to user-provided validation rules (i.e., using validationRules) since there would be no expectation that introspection was disabled.

The enforcement of user-provided validation rules on the HTTP transport is working as intended and is unaffected by this advisory. Similarly, disabling introspection on the HTTP transport is working as intended and is unaffected by this advisory.

> Note: Unless subscriptions: false is explicitly passed to the constructor parameters of new ApolloServer({ ... }), subscriptions are enabled by default, whether or not there is a Subscription type present in the schema. As an alternative to upgrading to a patched version, see the Workarounds section below to disable subscriptions if it is not necessary.

In cases where subscriptions: false is not explicitly set, the subscription server is impacted since validation rules which are enforced on the main request pipeline within Apollo Server were not being passed to the SubscriptionServer.create invocation (seen here, prior to the patch).

The omitted validation rules for the subscription server include any validationRules passed by implementors to the ApolloServer constructor which were expected to be enforced on the subscriptions WebSocket endpoint. Additionally, because an internal NoIntrospection validation rule is used to disable introspection, it would have been possible to introspect a server on the WebSocket endpoint that the SubscriptionServer creates even though it was not possible on other transports (e.g. HTTP).

The severity of risk depends on whether sensitive information is being stored in the schema itself. The contents of schema descriptions, or secrets which might be revealed by the names of types or field names within those types, will determine the risk to individual implementors.

Affected packages

The bug existed in apollo-server-core versions prior to version 2.14.2, however, this means all integration packages (e.g., apollo-server-express, etc.) prior to version 2.14.2 which depend on apollo-server-core for their subscriptions support are affected. This includes the apollo-server package that automatically provides an Express server.

Affected versions: < 2.14.2

Changelog

Sourced from apollo-server-express's changelog.

v2.14.2

Note: This release is is related to a GitHub Security Advisory published by the Apollo Server team. Please read the attached advisory to understand the impact.

v2.14.1

See complete versioning details.

v2.14.0

See complete versioning details.

  • apollo-server-core / apollo-server-plugin-base: Add support for willResolveField and corresponding end-handler within executionDidStart. This brings the remaining bit of functionality that was previously only available from graphql-extensions to the new plugin API. The graphql-extensions API (which was never documented) will be deprecated in Apollo Server 3.x. To see the documentation for the request pipeline API, see its documentation. For more details, see the attached PR. [PR #3988](apollographql/apollo-server#3988)

  • apollo-server-core: Deprecate graphql-extensions. All internal usages of the graphql-extensions API have been migrated to the request pipeline plugin API. For any implementor-supplied extensions, a deprecation warning will be printed once per-extension, per-server-startup, notifying of the intention to deprecate. Extensions should migrate to the plugin API, which is outlined in its documentation. [PR #4135](apollographql/apollo-server#4135)

  • apollo-engine-reporting: Currently only for non-federated graphs. Added an experimental schema reporting option, experimental_schemaReporting, for Apollo Graph Manager users. During this experiment, we'd appreciate testing and feedback from current and new users of the schema registry!

    Prior to the introduction of this feature, the only way to get schemas into the schema registry in Apollo Graph Manager was to use the CLI and run apollo schema:push. Apollo schema reporting protocol is a new specification for GraphQL servers to automatically report schemas to the Apollo Graph Manager schema registry.

    To enable schema reporting, provide a Graph Manager API key (available free from Apollo Graph Manager) in the APOLLO_KEY environment variable and set the experimental_schemaReporting option to true in the Apollo Server constructor options, like so:

    const server = new ApolloServer({
  typeDefs,
  resolvers,
  engine: {
    experimental_schemaReporting: true,
    /* Other existing options can remain the same. */
  },
});

    When enabled, a schema reporter is initiated by the apollo-engine-reporting agent. It will loop until the ApolloServer instance is stopped, periodically calling back to Apollo Graph Manager to send information. The life-cycle of this reporter is managed by the agent.

    For more details on the implementation of this new protocol, see the PR which introduced it to Apollo Server and the preview documentation.
