Two critical zero-day vulnerabilities are being actively exploited: CVE-2026-59310 impacting VMware vCenter (remote code execution) and CVE-2026-20349 affecting Cisco ASA/FTD (CVSS 8.6). Both are listed in CISA's KEV and have confirmed in-the-wild exploitation—with the VMware issue reported across 47 nations and a public proof-of-concept released—so organizations using these products are urged to apply mitigations immediately.
