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. • https://github.com/apollographql/router/commit/b295c103dd86c57c848397d32e8094edfa8502aa https://github.com/apollographql/router/releases/tag/v1.29.1 https://github.com/apollographql/router/security/advisories/GHSA-w8vq-3hf9-xppx • CWE-755: Improper Handling of Exceptional Conditions •
