GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

CVE-2021-23434 (GCVE-0-2021-23434)

Vulnerability from cvelistv5 – Published: 2021-08-27 16:50 – Updated: 2024-09-16 16:48
VLAI
Title
Prototype Pollution
Summary
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)
