apollo-server-core@3.6.4 vulnerabilities

apollo-server-core is a core module of the Apollo community GraphQL Server.

Affected versions of this package are vulnerable to Information Exposure when it can log sensitive information, such as Studio API keys, if they are passed incorrectly with leading/trailing whitespace or if they have any characters that are invalid as part of a header value.

Note Users are affected only if all the conditions are true:

• Use either the schema reporting or usage reporting feature.

• Use an Apollo Studio API key which has invalid header values.

• Use the default fetcher (node-fetch) or configure their own node-fetch fetcher

Upgrade apollo-server-core to version 2.26.1, 3.12.1 or higher.

apollo-server-core is a core module of the Apollo community GraphQL Server.

Affected versions of this package are vulnerable to Cache Poisoning when processing batch POST requests. The cache-control response header can be manipulated to cause data that should not be shared to be accessible by other clients via a reverse proxy such as a CDN, or by a browser.

Plugins assemble separate response headers in parallel for each operation in a batch, and then the header sets are merged together. If plugins set the same header on multiple operations, one value is chosen arbitrarily, and its cache policy is applied. This allows the responses from operations whose policy does not allow caching to be cached.

Upgrade apollo-server-core to version 3.11.0 or higher.

apollo-server-core is a core module of the Apollo community GraphQL Server.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the ApolloServerPluginLandingPageDefault() function in index.ts. When displaying a sample curl command on the default landing page, some browsers interpolate a received URL without escaping if it can't be fetched from the Apollo CDN.

NOTE: Several conditions must be met for this vulnerability to be exploited.

1. The affected user must use a browser like IE11, which doesn't URL-encode URLs retrieved from window.location.href.

2. The Apollo Server default landing page is enabled by passing ApolloServerPluginLandingPageLocalDefault(), ApolloServerPluginLandingPageProductionDefault(), or no value to the plugins option of new ApolloServer.

Upgrade apollo-server-core to version 3.10.1 or higher.

apollo-server-core is a core module of the Apollo community GraphQL Server.

Affected versions of this package are vulnerable to Denial of Service (DoS) by accepting an unbounded amount of memory in the cache.

NOTE: The size of a cache can be limited with the cache: "bounded" option as of version 3.9.0.

Upgrade apollo-server-core to version 3.9.0 or higher.
