almela obx before v.0.0.4 has a Prototype Pollution issue which allows arbitrary code execution via the obx/build/index.js:656), reduce (@almela/obx/build/index.js:470), Object.set (obx/build/index.js:269) component.
The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
