NewCVE-2026-80051 (opens in a new tab)How to fix?
There is no fixed version for github.com/graphql-go/graphql.
Overview
Affected versions of this package are vulnerable to Improper Validation of Specified Type of Input through the built-in coerceString and coerceBool scalar coercion functions in scalars.go. An attacker can trigger request handling errors or crash the process by supplying a scalar variable value whose runtime type does not match its declared String, ID, or Boolean GraphQL type. In some cases, a deeply nested value reaches an unrecoverable fatal error: stack overflow, breaking the service for users running the affected GraphQL server.
