> CISA identifies three actively exploited vulnerabilities in Arista EOS, Google Chromium V8, and Cisco SD-WAN Manager requiring urgent patching.

CISA has added three vulnerabilities with confirmed active exploitation to its Known Exploited Vulnerabilities (KEV) Catalog. CVE-2026-7473 affects Arista Extensible Operating System with an incomplete comparison flaw. CVE-2026-11645 is an out-of-bounds read/write vulnerability in Google Chromium's V8 engine. CVE-2026-20245 is an improper encoding or escaping issue in Cisco Catalyst SD-WAN Manager. All three carry active exploitation evidence and pose significant risk to federal networks and broader enterprise infrastructure.

Under Binding Operational Directive 22-01, Federal Civilian Executive Branch agencies must remediate these vulnerabilities by established due dates. CISA strongly recommends all organizations, regardless of federal status, prioritize remediation of KEV Catalog entries as part of standard vulnerability management. These vulnerabilities represent frequent attack vectors exploited by malicious cyber actors and should be treated as high-priority patching targets.
