Prototype Pollution in dset

Moderate severity GitHub Reviewed Published May 3, 2022 to the GitHub Advisory Database • Updated Feb 1, 2023

Package

npm dset (npm)

Affected versions

< 3.1.2

Patched versions

3.1.2
maven org.webjars.npm:dset (Maven)
< 3.1.2
3.1.2

Description

All versions of dset prior to 3.1.2 are vulnerable to Prototype Pollution via dset/merge mode, as the dset function checks for prototype pollution by validating if the top-level path contains __proto__, constructor or prototype. By crafting a malicious object, it is possible to bypass this check and achieve prototype pollution.

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.
