I dont have access to the upstream bug. However it seems this is related to 

https://chromium.googlesource.com/chromium/src/+/db8e2abccd737b0513a2cd11add50b543783f2da

Tomas, confirmed this is a part of the code we ship, calling it affected.

Why were we Qt/KDE maintainers put on CC for this bug? This is clearly a Chromium-specific vulnerability that cannot possibly affect QtWebKit or KHTML (because neither supports Pepper plugins). Only QtWebEngine can possibly be affected, but it is not currently in Fedora.
