CVE-2026-80051
github.com/graphql-go/graphql (GraphQL for Go) through 0.8.1 does not validate that a scalar variable value matches its declared type.
Overview
CVE-2026-80051 is a known-severity vulnerability. It was published on August 25, 2026.
Technical description
github.com/graphql-go/graphql (GraphQL for Go) through 0.8.1 does not validate that a scalar variable value matches its declared type. The built-in coerceString and coerceBool functions (scalars.go) accept input whose type does not match the declared String, ID, or Boolean scalar instead of raising the request error that the GraphQL specification mandates. In some cases (but not any typical case of JSON sent to a website), a deeply nested value leads to an unrecoverable "fatal error: stack overflow" condition.

How can CyberStrike help with CVE-2026-80051?
CyberStrike is an open-source, AI-augmented pentesting engine.
