CVE-2026-24888
January 28, 2026
Maker.js is a 2D vector line drawing and shape modeling for CNC and laser cutters. In versions up to and including 0.19.1, the "makerjs.extendObject" function copies properties from source objects without proper validation, potentially exposing applications to security risks. The function lacks "hasOwnProperty()" checks and does not filter dangerous keys, allowing inherited properties and potentially malicious properties to be copied to target objects. A patch is available in commit 85e0f12bd868974b891601a141974f929dec36b8, which is expected to be part of version 0.19.2.
