Opis:

The Apollo Router is a configurable, high-performance graph router written in Rust to run a federated supergraph that uses Apollo Federation 2. Affected versions are subject to a Denial-of-Service (DoS) type vulnerability which causes the Router to panic and terminate when GraphQL Subscriptions are enabled. It can be triggered when all of the following conditions are met: 1. Running Apollo Router v1.28.0, v1.28.1 or v1.29.0 ("impacted versions"); and 2. The Supergraph schema provided to the Router (either via Apollo Uplink or explicitly via other configuration) has a `subscription` type with root-fields defined; and 3. The YAML configuration provided to the Router has subscriptions enabled (they are _disabled_ by default), either by setting `enabled: true` _or_ by setting a valid `mode` within the `subscriptions` object (as seen in [subscriptions' documentation](https://www.apollographql.com/docs/router/executing-operations/subscription-support/#router-setup)); and 4. An [anonymous](https://spec.graphql.org/draft/#sec-Anonymous-Operation-Definitions) (i.e., un-named) `subscription` operation (e.g., `subscription { ... }`) is received by the Router If all four of these criteria are met, the impacted versions will panic and terminate. There is no data-privacy risk or sensitive-information exposure aspect to this vulnerability. This is fixed in Apollo Router v1.29.1. Users are advised to upgrade. Updating to v1.29.1 should be a clear and simple upgrade path for those running impacted versions. However, if Subscriptions are not necessary for your Graph ?? but are enabled via configuration ?? then disabling subscriptions is another option to mitigate the risk.
