CVE-2021-36044Network attack vector

Unauthenticated service interruption via GraphQL field

Published Sep 1, 2021 · Updated Sep 16, 2024

Improper input validation in Adobe Commerce 2.4.2-p1 and earlier allows remote attackers to interrupt service through a GraphQL field. Adobe identifies GraphQL field processing as the locus but has not disclosed the field, rejected value, or faulty validation operation. Unauthenticated network requests require no user interaction and affect availability only; the public record does not distinguish a hang from a crash.
