SS-2018-019: Possible denial of service attack vector when flushing

Moderate (?)
Versions Affected:
silverstripe/framework: ^4.0.0
Versions Fixed:
silverstripe/framework: 4.0.5, 4.1.3, 4.2.2, 4.3.0-rc1
Release Date:

A possible denial of service attack vector has been identified in the dev/build system controller.

dev/build now has its own URL token, similar to flushtoken, to ensure users are authenticated when running dev/build outside of dev environments.
