Vulnerability from github – Published: 2021-09-01 18:37 – Updated: 2023-09-08 21:25

Summary
Prototype Pollution in object-path
Details
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.
Severity
5.6 (Medium)
