CISA just issued a stark warning: two widely discussed “zero-day” vulnerabilities are not theoretical anymore—there’s evidence they’re actively being exploited in the wild. Both have now been added to CISA’s KEV (Known Exploited Vulnerabilities) catalog, and federal agencies are required to remediate fast—no later than Oct 16—otherwise they risk more intrusions and data exposure. The two zero-days: 1) Microsoft Windows command injection: CVE-2026-96951. Attackers may craft specific requests that trigger unplanned command execution, setting up the next steps like lateral movement, credential theft, or malware deployment. CISA says exploit activity has already been observed. 2) Ivanti Connect Secure (ICS) auth bypass: CVE-2026-104935. Even if authentication appears required, the verification flow can be bypassed, enabling unauthorized access. Once attackers get in, they can rapidly pivot from exploitation to privilege expansion. Microsoft and Ivanti have released fixes in October’s regular security updates. If you manage endpoints, servers, or remote access: prioritize patching, confirm it landed, and review exposed assets + logs for signs of compromise. #CyberSecurity #CISA #ZeroDay #KEV #VulnerabilityManagement #IncidentResponse
