Not CVE-worthy, as the use case clearly falls outside of the documented / declared area of application.

It deserves a major release, because it breaks compatibility. A capability that used to work (i.e,. loading a large but trusted file) no longer works. It may not affect everyone, but when assessing impact, we go for the most conservative evaluation.
