DescriptionNVD

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.

AnalysisAI

This affects the package object-path before 0.11.6. Rated high severity (CVSS 8.6), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.

Technical ContextAI

This vulnerability is classified as Access of Resource Using Incompatible Type (Type Confusion) (CWE-843), which allows attackers to execute arbitrary code by exploiting type confusion in the application. 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. Affected products include: Object-Path Project Object-Path, Debian Debian Linux. Version information: before 0.11.6..

RemediationAI

A vendor patch is available. Apply the latest security update as soon as possible. Enforce strict type checking, use type-safe languages, validate object types before operations.
