Reviewed core security vulnerability patch and wrote test. Reviewed and coordinated SA releases.
Shared part of the code used to lock the Managed Cloud Workflow UI when a long task is triggered, built as a standalone module that displays an overlay layer blurring the screen, with a nice spinner in the middle.
