Summary

@nevware21/ts-utils is a comprehensive TypeScript/JavaScript utility library. Prior to version 0.14.0, the _copyProps function in lib/src/object/copy.ts uses for...in to iterate over source object properties without an Object.hasOwnProperty check, and does not filter dangerous keys (__proto__, constructor, prototype).

This allows an attacker to pollute the prototype chain of all objects in the application. Version 0.14.0 patches the issue.

This vulnerability allows a remote attacker to manipulate the fundamental properties of objects within an application. By exploiting this, an attacker could potentially execute unauthorized code, leading to a complete compromise of the application.

This vulnerability is rated as Important. This could lead to arbitrary code execution within applications utilizing the affected library, impacting data integrity and potentially system availability.

Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N). Weakness: CWE-915.

Affected Red Hat products: Red Hat OpenShift Dev Spaces 3.30. Red Hat lists Red Hat OpenShift AI (RHOAI) as not affected.

Red Hat fixing advisory: RHSA-2026:62260.
