**Version of dependency-check used**
13.0.0 via Gradle

**To Reproduce**
Will attach better steps later, but scan a POm with the above dependency in it with OSSindex credentials set should be enough.

**Expected behavior**
Vulns should be able to be parsed

**Additional context**
The code seems to be falling back to a CVSS2 parse and then seeing an L for CIA type, which is invalid. Probably need to check the raw response and figure out if the data is bad, or the parsing is bad.
