Plotly Security Advisory - XSS in plotly.js

Summary of issue

A Cross-Site Scripting (XSS) vulnerability has been fixed in the plotly.js library.

An attacker can trick an unsuspecting user into viewing a specially crafted plot, then moving the mouse over a certain part of the plot, on a site that uses plotly.js (including the cloud version of Chart Studio). The vulnerability would have allowed the attacker to perform any action using the victim’s credentials on that site.
