GMS-2020-726: Cross-Site Scripting in google-closure-library

September 2, 2020 (updated September 27, 2021)

Versions of google-closure-library prior to 20190301.0.0 are vulnerable to Cross-Site Scripting. The safedomtreeprocessor.processToString() function improperly processed empty elements, which could allow attackers to execute arbitrary JavaScript through Mutation Cross-Site Scripting.

Recommendation

Upgrade to version 20190301.0.0 or later.
