Blender: 4.2.23 → 4.5.15

Upgrade impact: Minor upgrade. Minor releases are usually backwards-compatible, but can add or change behaviour — test in staging before production.

Fixed by upgrading to 4.5.15 iVulnerabilities that affect 4.2.23 but no longer affect 4.5.15 — the security gain from this upgrade, by exploited status then exploitation probability.

Exploited first, then by exploitation probability (EPSS).
