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.
This affects the package object-path before 0.11.6. A type confusion vulnerability can lead to a bypass of CVE-2020-15256 when the path components used in the path parameter are arrays. In particular, the condition currentPath === 'proto' returns false if currentPath is ['proto']. This is because the === operator returns always false when the type of the operands is different.
