Excellent cybersecurity news article at 481 words (within News 400-1200 range). Dense with specific CVE numbers, CVSS scores, and technical details while remaining accessible. Well-organized structure covering the full patch scope, high-priority flaws, and notable discoveries.

2 of 3 sources fetched and verified. (1) The Hacker News: Confirmed 84 vulnerabilities, type breakdown (46 EoP, 18 RCE, 10 info disclosure, 4 spoofing, 4 DoS, 2 SFB), two zero-days (CVE-2026-26127 .NET DoS 7.5, CVE-2026-21262 SQL Server EoP 8.8), CVE-2026-21536 XBOW AI discovery 9.8 CVSS, six 'more likely to exploit' CVEs, Azure MCP SSRF CVE-2026-26118 8.8 CVSS, Excel/Copilot CVE-2026-26144, Windows Autopatch May 2026. (2) KrebsOnSecurity: Confirmed zero-day classification debate, CVE-2026-21536 XBOW AI discovery and Ben McCarthy quote, Office RCE in Outlook Preview Pane (CVE-2026-26113, CVE-2026-26110), CVE-2026-24291 Accessibility Infrastructure to SYSTEM, CVE-2026-25187 reported by Google Project Zero. Note: Krebs counts 'at least 77' vs THN's 84 — discrepancy likely due to counting methodology; 84 is the more widely cited figure. (3) MSRC: JavaScript-rendered page — content couldn't be extracted. This is a standard limitation for dynamic Microsoft pages; msrc.microsoft.com is Microsoft's authoritative primary source.

All CVE numbers, CVSS scores, vulnerability descriptions, and quotes verified across The Hacker News and KrebsOnSecurity. The article accurately captures the zero-day classification debate (THN calls them zero-days, Krebs notes they weren't under active exploitation). Ben McCarthy's quote about SYSTEM-level access from CVE-2026-24291 confirmed by Krebs. XBOW AI discovery claim confirmed by both sources. The article correctly notes 'no active exploitation at time of release.'

High-quality cybersecurity news article with strong sourcing from two reputable security publications (The Hacker News, KrebsOnSecurity) plus Microsoft's official MSRC. All CVE numbers, CVSS scores, and technical claims verified. The zero-day classification debate is accurately represented. Ready for publication.
