‼️ CISA Confirms Active Exploitation of Outlook User Interaction 0-Day Vulnerability Details: https://t.co/9hqn7XHeqI The U.S. Cybersecurity and Infrastructure Security Agency has confirmed active exploitation of a Microsoft Outlook zero-day vulnerability, CVE-2026-124194, that can expose user authentication data. According to Microsoft’s security advisory, an attacker can send a specially crafted message file and persuade a victim to open it in Outlook. The application may then connect to an attacker-controlled network location without showing its usual warning about external content. Microsoft released security updates for an actively exploited Outlook network-spoofing flaw (CVSS 6.5) that allows unauthenticated attackers to spoof networks. #CybersecurityNews
