CVE-2018-1000086

Name of the Vulnerable Software and Affected Versions: Pym.js versions 0.4.2 through 1.3.1

Description: The issue concerns a Cross Site Request Forgery (CSRF) vulnerability in the onNavigateToMessage function of Pym.js. This can result in arbitrary JavaScript code execution. The attack is exploitable when an attacker gains full JavaScript access to pages with Pym.js embeds or when a user visits an attacker-crafted page.

Recommendations: For Pym.js versions 0.4.2 through 1.3.1, update to version 1.3.2 or later to resolve the issue. As a temporary workaround, consider disabling the onNavigateToMessage function until a patch is available.
