Vulnerability Overview

The package json5 before 1.0.2 and between 2.0.0 and 2.2.1 inclusive is vulnerable to prototype pollution due to failure to restrict parsing of keys named `__proto__`. As this package is used in some WordPress plugins, this could result in the impacted plugins being vulnerable.

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')

The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.

Update to version 1.1.0, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Block for Apple Maps 1.1.0 closes this, and updating the plugin is the step that ends it.
