#8180 e9d49d1 Thanks @github-actions! - ⚠️ SECURITY @apollo/server/standalone:
The default configuration of startStandaloneServer was vulnerable to denial of service (DoS) attacks through specially crafted request bodies with exotic character set encodings.
In accordance with RFC 7159, we now only accept request bodies encoded in UTF-8, UTF-16 (LE or BE), or UTF-32 (LE or BE).
Any other character set will be rejected with a 415 Unsupported Media Type error.
Additionally, upstream libraries used by this version of Apollo Server may not support all of these encodings, so some requests may still fail even if they pass this check.
If you were not using startStandaloneServer, you were not affected by this vulnerability.
Generally, please note that we provide startStandaloneServer as a convenience tool for quickly getting started with Apollo Server.
For production deployments, we recommend using Apollo Server with a more fully-featured web server framework such as Express, Koa, or Fastify, where you have more control over security-related configuration options.
Also please note that Apollo Server 4.x is considered EOL as of January 26, 2026, and Apollo no longer commits to providing support or updates for it. Please prioritize migrating to Apollo Server 5.x for continued support and updates.
