    Apollo Compiler Named Fragment Processing Vulnerability

    Issue
    Impact Summary A vulnerability in Apollo Compiler allowed queries with deeply nested and reused named fragments to be prohibitively expensive to validate. This could lead to excessive resource consumption and denial of service in applications. Details Named fragments were being processed once per fragment spread in some cases during query validation, leading to exponential resource usage when deeply nested and reused fragments were involved. Fix/Mitigation The validation logic has been updated to process each named fragment only once, preventing redundant traversal. Patches This has been remediated in apollo-compiler version 1.27.0. Workarounds No known direct workarounds exist. Acknowledgements We appreciate the efforts of the security community in identifying and improving the performance and security of query validation mechanisms.

    Recommended action: Upgrade to 1.27.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
