Description

Handlebars.js enables prototype pollution

Date

15 Feb 2019

Severity

3 - HIGH

CVSSv3 score

CVSSv3 score not available on NIST NVD.

Status

✅ 2.3.4

Assessment

The Handlebars.js Node.js module versions 4.0.12 and earlier make it possible for an attacker to modify the __proto__ accessor property.

Modified properties are propagated through inheritance to all objects.

This enables arbitrary adding or modifying object prototype properties, and arbitrary code execution on the targeted server.

Mitigation

Update to Handlebars.js 4.0.13 or later.

Affected versions

2.3.0 to 2.3.3 included.
