moderate severity GitHub Reviewed Published Nov 9, 2018 • Updated Sep 16, 2021

Package

npm mapbox.js (npm)

Affected versions

< 1.6.5
>= 2.0.0, < 2.1.7

Patched versions

2.1.7

Description

Versions 1.x prior to 1.6.5 and 2.x prior to 2.1.7 of mapbox.js are vulnerable to a cross-site-scripting attack in certain uncommon usage scenarios.

If L.mapbox.map or L.mapbox.tileLayer are used to load untrusted TileJSON content from a non-Mapbox URL, it is possible for a malicious user with control over the TileJSON content to inject script content into the "attribution" value of the TileJSON which will be executed in the context of the page using Mapbox.js.

Recommendation

Version 2.x: Update to version 2.1.7 or later.
Version 1.x: Update to version 1.6.5 or later.
