CVE-2026-23897
Impact
The default configuration of
startStandaloneServerfrom@apollo/server/standaloneis vulnerable to Denial of Service (DoS) attacks through specially crafted request bodies with exotic character set encodings.This issue does not affect users that use
@apollo/serveras a dependency for integration packages, like@as integrations/express5or@as-integrations/next, only direct usage ofstartStandaloneServer.Who is impacted
Users directly using
startStandaloneServerfrom@apollo/server/standalone.This issue affects Apollo Server from v5.0.0 through v5.3.x.
It also affects all releases of the end-of-life major versions v4, v3, and v2. Although Apollo Server v4 is EOL and Apollo no longer commits to providing support or updates for it, a fix for it was released in v4.13.0. Apollo Server v3 and v2 are no longer updated, as they have been EOL since 2024 and 2023 respectively.
Patches
Patches for this issue are released as
@apollo/serverversions5.4.0and4.13.0.In accordance with RFC 7159, these versions 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 Typeerror. Note that the more recent JSON RFC, [RFC 8259 (https://datatracker.ietf.org/doc/html/rfc8259#section-8.1), is more strict and will only allow UTF-8. Since this is a minor release, we have chosen to remain compatible with the more permissive RFC 7159 for now. In a future major release, the restriction may be tightened further to only allow UTF-8.Workarounds
Users of
apollo-serverv2 or v3 that cannot upgrade for some reason could switch from the standaloneapollo-serverpackage to an integration package like
apollo-server-expressorapollo-server-koaand set up their own server. Please note that these old packages are generally EOL and do not receive any more support or bug fixes. This can only be seen as a short-term workaround. Updating to@apollo/serverv5 should be a priority.Release Notes

#8180⚠️ SECURITY
e9d49d1Thanks @github-actions! -@apollo/server/standalone:The default configuration of
startStandaloneServerwas 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 Typeerror.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
startStandaloneServeras 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.
