CVE-2020-15256 Information

Description

A prototype pollution vulnerability has been found in object-path = 0.11.4 affecting the set() method. The vulnerability is limited to the includeInheritedProps mode (if version = 0.11.0 is used) which has to be explicitly enabled by creating a new instance of object-path and setting the option includeInheritedProps: true or by using the default withInheritedProps instance. The default operating mode is not affected by the vulnerability if version = 0.11.0 is used. Any usage of set() in versions 0.11.0 is vulnerable. The issue is fixed in object-path version 0.11.5 As a workaround don’t use the includeInheritedProps: true options or the withInheritedProps instance if using a version = 0.11.0.
