Prototype Pollution
CVE-2021-23434
5.6MEDIUM
What is CVE-2021-23434?
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.
