CVE-2020-15256

Impact

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.

Patches

Upgrade to version >= 0.11.5

Workarounds

Don't use the includeInheritedProps: true options or the withInheritedProps instance if using a version >= 0.11.0.
