Clarify that CVE-2025-49651 (direct compute node access via port scanning) is not a software vulnerability but an operational security requirement. Backend.AI assumes compute nodes are deployed in network-isolated environments with inbound access restricted to App Proxy components only. This entry references the comprehensive network security documentation added in #7587. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
