Descripción técnica

GraphQL Tools provides utilities for building, stitching, and mocking GraphQL schemas. From 10.10.1 until 12.0.2, the @graphql-tools/utils mergeIncrementalResult helper passes incrementalResult.path segments to setObjectKeyPath without runtime primitive-type validation. A non-primitive segment can bypass strict comparisons against __proto__, constructor, and prototype, then be coerced during property access so a malicious or compromised upstream incremental GraphQL response writes attacker-controlled properties to Object.prototype in the consuming Node.js process. The affected implementation is packages/utils/src/mergeIncrementalResult.ts and is reachable when consumers merge untrusted @defer or @stream transport results. This issue is fixed in version 12.0.2.

——8Joi 17.13.6 before 17.13.9 and 18.2.5 before 18.3.1 contains a prototype pollution vulnerability in lib/messages.js compile() and merge() that fails to reject a __proto__ language key. Attackers supplying untrusted message configuration via any().messages(), prefs, validate options or Joi.extend can replace the compiled messages prototype, altering or breaking validation error rendering and dependent logic.9h CVE-2026-1157626.1 MED

——2draw.io is a configurable diagramming and whiteboarding application. Prior to 31.1.5, the GraphML decoder contains a prototype-pollution vulnerability. Attacker-controlled GraphML reference keys can address inherited object properties, including prototype objects, and the decoder can then assign attacker-controlled attributes to those objects. Importing a malicious GraphML file can trigger client-side prototype pollution. In the advisory-supported cross-site scripting chain, the editor is opened in Trello mode and the user invokes the Trello integration after the import, allowing the polluted state to execute script in the draw.io origin; an existing Trello connection is not required. This vulnerability is fixed in 31.1.5.1d CVE-2026-1219655.3 MED

——11Parse Server before 8.6.113 and 9.0.0 before 9.10.6-alpha.5 contains a prototype pollution vulnerability when building objects for Cloud Code triggers and LiveQuery, where a dot notation key whose intermediate segment resolves through an inherited member writes onto a process-wide built-in. Clients with write access to an object in a class with a trigger or LiveQuery can corrupt a built-in function, making unrelated requests fail until restart and denying service to all clients and hosted applications.1d CVE-2026-634025.9 MED

——6i18next is an internationalization framework for JavaScript. Prior to version 26.3.4, `deepExtend` in `src/utils.js` checks property existence with the in operator and recurses into inherited built-ins reached through `Object.prototype`. An application must explicitly pass attacker-controlled resource data to `addResourceBundle(lng, ns, data, deep, overwrite)` with both `deep: true` and `overwrite: true`. Source keys such as `hasOwnProperty`, `toString` and `valueOf` can then select shared inherited built-in function objects, and a nested value can overwrite a property of those objects process-wide. For example, making `Object.prototype.hasOwnProperty.call` non-callable causes subsequent uses, including i18next internals, to throw TypeError, resulting in unrecoverable denial of service and limited integrity impact. The `__proto__`/`constructor` guard does not prevent this mechanism because the corruption target is an inherited built-in function rather than the prototype object itself. Default calls without deep merging or with overwrite falsy are unaffected, and no standard i18next backend or integration uses the vulnerable configuration. This issue is distinct from the setPath/key-walking prototype-pollution flaws in i18next-fs-backend (CVE-2026-48713) and i18next-http-middleware (CVE-2026-48714). This issue is fixed in version 26.3.4.1d CVE-2026-1195695.3 MED

——10Parse Server before 8.6.108 and 9.0.0 before 9.10.5-alpha.9 contains a prototype pollution vulnerability because user-controlled keys are expanded into objects without own-property checks. Clients with class write access can send dot notation field keys or ACL entry names matching built-in object members to corrupt built-in functions, causing all requests to fail until server restart.7d CVE-2026-1187774.8 MED

——6Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.1, the forge.http client stored cookie names and paths from Set-Cookie response headers in ordinary JavaScript objects. A malicious server could use the cookie name __proto__ so that the attacker-controlled cookie path was written as a property on Object.prototype, or use inherited names such as constructor to modify Object. An empty cookie value could use the removal path to delete an inherited Object.prototype property. Applications using forge.http directly or through forge.xhr are affected; applications that do not use forge.http are unaffected. This issue is fixed in version 1.4.1.2d
