CISA adds Microsoft Windows CVE-2026-96951 and Ivanti Connect Secure CVE-2026-104935 to KEV catalog over active exploitation
CISA added two vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog based on evidence of active exploitation: CVE-2026-96951, a command injection flaw in Microsoft Windows, and CVE-2026-104935, an authentication bypass by spoofing in Ivanti Connect Secure. CISA describes these vulnerability types as a frequent attack vector for malicious cyber actors and a significant risk to the federal enterprise. The alert gives no technical exploitation details, threat actor attribution, victim information or IOCs. It restates the requirements of BOD 26-04 for Federal Civilian Executive Branch (FCEB) agencies, and CISA encourages all organizations to adopt risk-based vulnerability management and prioritize KEV remediation.
Technical Details
- CVE-2026-96951: Microsoft Windows Command Injection Vulnerability.
- CVE-2026-104935: Ivanti Connect Secure Authentication Bypass by Spoofing Vulnerability.
- The article does not list affected versions or exploitation methods.
Remediation
- Under BOD 26-04, FCEB agencies must prioritize rapid remediation of KEV-listed CVEs on publicly exposed assets that grant total control of the asset after exploitation.
- BOD 26-04 also sets basic expectations for when agencies must check whether threat actors compromised a system before the patch was applied.
- CISA encourages all organizations to prioritize remediation of KEV Catalog vulnerabilities.
- The article gives no specific patch or mitigation guidance; consult the vendor advisories.
