Outdated and vulnerable v8 is used

This issue is unique.

• I have used the search tool and did not find an issue describing my idea.

Your idea.

The javascript engine v8, version 8.9(used in https://github.com/ONLYOFFICE/build_tools/blob/master/scripts/core_common/modules/v8_89.py) is very outdated and vulnerable.

It should be updated to a recent version or have security patches backported.

For reference, qt5-webengine uses chromium 87 and v8 8.7 with some added security patches. The commits are available here: https://github.com/qt/qtwebengine-chromium/commits/87-based/

The cef binary, downloaded from http://d2ettrnqo7v976.cloudfront.net/cef/5414/linux_64/cef_binary.7z in https://github.com/ONLYOFFICE/build_tools/blob/master/scripts/core_common/modules/cef.py also appears to be very outdated.

And seriously, why is it downloaded from an HTTP url without any checksumming?

also appears to be very outdated.

The CEF used is branch 5414, which gives chromium version 109. Really outdated. Being CEF a core component of the user interface functionality, it's a concern.

Also, I would like to see the source code of this CEF published in an OnlyOffice repository, as it seems to be a modified build of the upstream CEF (Dektop Editors segfaults when trying to use an offical CEF build). Please correct me if I'm wrong.
