DescriptionGitHub Advisory

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.

AnalysisAI

Maker.js versions up to 0.19.1 improperly validate object properties in the extendObject function, allowing inherited and malicious properties to be copied to target objects without filtering. Applications using the library are vulnerable to property injection attacks, and public exploit code exists for this vulnerability. A patch is available in version 0.19.2.
