deep-object-diff vulnerable to Prototype Pollution

Moderate severity GitHub Reviewed Published Nov 4, 2022 to the GitHub Advisory Database • Updated Jan 28, 2023

Package

npm deep-object-diff (npm)

Affected versions

>= 1.1.6, < 1.1.9

Patched versions

1.1.9

Description

deep-object-diff before version 1.1.6 allows an external attacker to edit or add new properties to an object. This is possible because the application does not properly validate incoming JSON keys, thus allowing the __proto__ property to be edited. This issue was fixed in version 1.1.9.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
