Release Notes

ardatan/graphql-tools (@​graphql-tools/utils)

v12.0.3

Compare Source

Patch Changes

• #​8482 19f5b33 Thanks @​ardatan! - Compare incremental path keys to __proto__ at the property access in setObjectKeyPath, in addition to the existing isSafeObjectKey check.

v12.0.2

Compare Source

Patch Changes

• #​8456 b1fbba2 Thanks @​renovate! - dependencies updates:

  • Updated dependency @whatwg-node/promise-helpers@^2.0.0 ↗︎ (from ^1.0.0, in dependencies)

• #​8467 20d36a5 Thanks @​ardatan! - Fix prototype pollution in mergeIncrementalResult

  Path segments are now rejected unless they are primitive strings or numbers, and keys named __proto__, constructor or prototype are still blocked. Previously a non-primitive segment such as ["__proto__"] bypassed the string equality guard and was coerced into a write on Object.prototype.

  Also exports shared isSafeObjectKey / isDangerousObjectKey helpers used by this path walker and other package call sites. @graphql-tools/merge and @graphql-tools/mock are patched so they ship with the new imports; updateInternalDependencies raises their utils floor when 12.0.2 is versioned.
