A vulnerability, which was classified as problematic, was found in nortikin Sverchok 1.3.0. Affected is the function SvSetPropNodeMK2 of the file sverchok/nodes/object_nodes/getsetprop_mk2.py of the component Set Property Mk2 Node. The manipulation leads to improperly controlled modification of object prototype attributes ('prototype pollution'). It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
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.
