Subject: [PATCH 02/17] Added input validation for TPS
The TPSProfileService has been modified to validate the
profile ID and profile property names received via REST API.
The TPS UI has been modified to validate profile ID and
profile property names before they are sent to the server.
The TableItem.renderColumn() has been modified to escape
the value already stored in the database before displaying
it in the UI.

Subject: [PATCH 06/17] Re-fix sanitization in CMSTemplate
When fixing CVE-2019-10179 originally in
8884b4344225bd6656876d9e2a58b3268e9a899b,
I had switched to Apache Commons Lang2's
sanitization framework. However, I didn't
enable the HTML sanitization necessary to
fix this CVE.
