What happened
CISA added multiple vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog (May 1–20, 2026), based on evidence of active exploitation. New entries affect Microsoft (including Defender, Exchange, Internet Explorer, Windows), Adobe Acrobat/Reader, Linux kernel, Cisco Catalyst SD‑WAN, Palo Alto PAN‑OS, Ivanti EPMM, and BerriAI LiteLLM. CISA reminds organizations of Binding Operational Directive (BOD) 22‑01 requirements for remediation and urges timely mitigation for all KEV items.
