affectedVersionStart property
The version number at the start of an interval in which this vulnerability exists.
A vulnerability can affect a package between version numbers that are disjoint sets of intervals (example: [1.0.0-1.1.0], [2.4.6-2.4.8] and [4.5.6-4.6.8]) each of which will be represented in its own Detail. If a specific affected version is provided by a vulnerability database, affected_version_start and affected_version_end will be the same in that Detail.
Implementation
Version? affectedVersionStart;
