Impact

What kind of vulnerability is it?

Apollo Server can log sensitive information (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.

Who is impacted?

Users who (all of the below):

• 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 configured their own node-fetch fetcher

The following node snippet can test whether your API key has invalid header values. This code is taken directly from node-fetch@2's header value validation code.

const invalidHeaderCharRegex = /[^\t\x20-\x7e\x80-\xff]/;
if (invalidHeaderCharRegex.test('<YOUR_API_KEY>')) {
  console.log('potentially affected');
}
console.log('unaffected');

If the provided API key is not a valid header value, whenever Apollo Server uses that API key in a request (to Studio, for example), node-fetch will throw an error which contains the header value. This error is logged in various ways depending on the user's configuration, but most likely the console or some configured logging service.

Patches

This problem is patched in the latest version of Apollo Server as soon as this advisory is published.

Workarounds

• Try retrieving a new API key from Studio. Note: this may not work if the invalid character is not part of the secret (it may be derived from identifiers like graph name, user name).
• Override the fetcher
• Disable schema reporting and/or usage reporting

Solution

• Apollo Server will now call .trim() on incoming API keys in order to eliminate leading/trailing whitespace and log a warning when it does so.
• Apollo Server will now perform the same validation of API keys as node-fetch@2 performs on header values on startup. Apollo Server will throw an error on startup (i.e., fail to start completely) and notify the user their API key is invalid along with the offending characters.

v4.9.3

Compare Source

Patch Changes

• a1c725eaf Thanks @​trevor-scheer! - Ensure API keys are valid header values on startup

  Apollo Server previously performed no sanitization or validation of API keys on startup. In the case that an API key was provided which contained characters that are invalid as header values, Apollo Server could inadvertently log the API key in cleartext.

  This only affected users who:

  • Provide an API key with characters that are invalid as header values
  • Use either schema or usage reporting
  • Use the default fetcher provided by Apollo Server or configure their own node-fetch fetcher

  Apollo Server now trims whitespace from API keys and validates that they are valid header values. If an invalid API key is provided, Apollo Server will throw an error on startup.

Patch Changes

• #​7699 62e7d940d Thanks @​trevor-scheer! - Fix error path attachment for list items

  Previously, when errors occurred while resolving a list item, the trace builder would fail to place the error at the correct path and just default to the root node with a warning message:

  Could not find node with path x.y.1, defaulting to put errors on root node.

  This change places these errors at their correct paths and removes the log.

Minor Changes

• #​7617 4ff81ca50 Thanks @​trevor-scheer! - Introduce new ApolloServerPluginSubscriptionCallback plugin. This plugin implements the subscription callback protocol which is used by Apollo Router. This feature implements subscriptions over HTTP via a callback URL which Apollo Router registers with Apollo Server. This feature is currently in preview and is subject to change.

  You can enable callback subscriptions like so:

  import { ApolloServerPluginSubscriptionCallback } from '@​apollo/server/plugin/subscriptionCallback';
  import { ApolloServer } from '@​apollo/server';
  
  const server = new ApolloServer({
    // ...
    plugins: [ApolloServerPluginSubscriptionCallback()],
  });

  Note that there is currently no tracing or metrics mechanism in place for callback subscriptions. Additionally, this plugin "intercepts" callback subscription requests and bypasses some of Apollo Server's internals. The result of this is that certain plugin hooks (notably executionDidStart and willResolveField) will not be called when handling callback subscription requests or when sending subscription events.

  For more information on the subscription callback protocol, visit the docs:
