    CVE-2026-23897 (GCVE-0-2026-23897)

    Vulnerability from nvd – Published: 2026-02-04 19:18 – Updated: 2026-02-04 19:55

    Title
    Apollo Server is vulnerable to denial of service with `startStandaloneServer`
    Summary
    Apollo Server is an open-source, spec-compliant GraphQL server that's compatible with any GraphQL client, including Apollo Client. In versions from 2.0.0 to 3.13.0, 4.2.0 to before 4.13.0, and 5.0.0 to before 5.4.0, the default configuration of startStandaloneServer from @apollo/server/standalone is 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/server as a dependency for integration packages, like @as-integrations/express5 or @as-integrations/next, only direct usage of startStandaloneServer.
