What is CVE-2024-28101?

The Apollo Router, developed in Rust for navigating a federated supergraph using Apollo Federation, is susceptible to a Denial-of-Service vulnerability in versions ranging from 0.9.5 to 1.40.2. This vulnerability arises when the Router processes compressed HTTP payloads, evaluating the configuration setting limits.http_max_request_bytes only after the complete payload is decompressed. As a result, if the Router receives a highly compressed payload, it can lead to excessive memory usage during decompression, potentially causing service disruptions. Version 1.40.2 has addressed this issue. Users who cannot promptly upgrade may implement mitigations through configurations at proxies, load balancers, or cloud-native WAF services, setting limits on the size of HTTP body uploads.
