Apollo Router's Compressed Payloads do not respect HTTP Payload Limits

The Apollo Router is a graph router written in Rust to run a federated supergraph that uses Apollo Federation. Versions 0.9.5 until 1.40.2 are subject to a Denial-of-Service (DoS) type vulnerability. When receiving compressed HTTP payloads, affected versions of the Router evaluate the `limits.http_max_request_bytes` configuration option after the entirety of the compressed payload is decompressed. If affected versions of the Router receive highly compressed payloads, this could result in significant memory consumption while the compressed payload is expanded. Router version 1.40.2 has a fix for the vulnerability. Those who are unable to upgrade may be able to implement mitigations at proxies or load balancers positioned in front of their Router fleet (e.g. Nginx, HAProxy, or cloud-native WAF services) by creating limits on HTTP body upload size.

Apollo Router 安全漏洞

Apollo Router是一个用 Rust 编写的可配置的高性能图形路由器。 Apollo Router 0.9.5 到 1.40.2版本存在安全漏洞，该漏洞源于压缩有效载荷不遵守HTTP 有效载荷限制，导致拒绝服务。
