Oliver Kieselbach fbe03af14f fix(backend/vuln): CVE-Cache EntityTooLarge — date+severity budget caps per-CPE row
Nightly VulnerabilityDataSync at 03:00 UTC was hitting Azure Table Storage's
1 MB per-entity ceiling on popular CPEs (browsers, Chromium-mass-release CVEs,
Windows components with hundreds of CPE matches). Property-chunking only
guards the 64 KB per-property bound, not the row total.

New CveCacheBudget filters before the cache write so a row can never grow past
the limit:
- date floor: last 24 months (all severities) + last 60 months for CVSS >= 7.0
  (keeps current HIGH/CRITICAL findings for LTS software like Java 8 / .NET FX)
- sort CVSS desc, PublishedDate desc, cap 100 CVEs
- per-CVE: cap AffectedVersions at 50 ranges
- unparseable PublishedDate -> keep (conservative)

Both write paths (VulnerabilityCorrelationService.FetchAndCacheCvesFromNvdAsync
and VulnerabilityDataSyncFunction.RefreshStaleCveCacheAsync) go through the same
helper; the sync path also drops the blind .Take(200) and now logs total/
date-filtered/truncated-ranges/bytes per CPE so we can watch the budget land.

Read path is unchanged — older oversized rows continue to work via the existing
TableStorageChunking reassembly until they expire and get refreshed under the
new budget.

Tests: 1990/1990 green; 10 new CveCacheBudgetTests cover the date floor,
LTS-rescue window, sort+cap, AffectedVersions truncation, and edge cases.

Autopilot Monitor

Status License Website

Advanced monitoring and troubleshooting solution for Windows Autopilot deployments. Gain full visibility into every enrollment session with a detailed event timeline, fleet health dashboards, and session reporting. Define custom analysis rules to automatically detect issues and gather rules to collect targeted evidence. Retrieve diagnostics packages on demand, configure agent settings like auto-reboot behavior and automatic timezone adjustment — all managed centrally from the web dashboard.

Private Preview

Autopilot Monitor is currently running as a Private Preview. Visit autopilotmonitor.com to request access and learn more.

Overview

Autopilot Monitor provides real-time tracking, intelligent diagnostics, and automated troubleshooting for Windows Autopilot enrollment processes. It consists of:

  • Bootstrap Script — PowerShell script deployed via Intune that starts monitoring early in the enrollment process
  • Monitoring Agent — Lightweight .NET application that collects telemetry and evidence during enrollment
  • Backend API — Azure Functions-based ingestion and processing pipeline
  • Web Dashboard — Next.js application for real-time monitoring and fleet analytics

Architecture
