Week in Security: Exchange Zero-Day Exploited, NPM Worm Surges, and AI Supply-Chain Risks
This weekly security roundup highlights rapid, multi-vector threats: on-prem Microsoft Exchange is being exploited via CVE-2026-42897 (spoofing/XSS), Cisco’s SD-WAN Controller faces active exploitation from CVE-2026-20182, and a TeamPCP‑driven wave poisons TanStack npm packages as part of a larger supply-chain campaign. The era of fake AI repos delivering stealer malware continues (Open-OSS/privacy-filter on Hugging Face). AI-assisted vulnerability discovery is accelerating with OpenAI’s Daybreak and Microsoft MDASH, alongside other notable findings (ransomware deals, new CVEs, and cross‑platform E2EE deployments). The takeaway: patch early, rotate keys, and assume software supply chains are compromised.
