  A critical vulnerability blitz dominates this digest: Oracle PeopleSoft CVE-2026-35273, Splunk CVE-2026-20253, and an unpatched Microsoft Defender RoguePlanet zero-day are actively exploited, with ShinyHunters and other threat actors targeting higher education and enterprise networks. The AI/security layer has emerged as a major attack surface, exemplified by Microsoft 365 Copilot SearchLeak (one-click data exfiltration), Google Vertex AI cross-tenant RCE, and the Novo Nordisk breach that exposed proprietary AI model checkpoints and training infrastructure as ransomware extortion payload—underscoring that AI IP is now a strategic target.
