DETAILS: Fortinet has issued a warning regarding a critical flaw in FortiMail email security appliances The vulnerability is actively exploited in zero-day attacks (in-the-wild exploitation prior to patch availability) No CVE identifier, attack vector, or technical description is available in sourced reporting at this time Patch status and affected version numbers not yet confirmed in available material Timeline of discovery and exploitation window unclear IMPACT: ...

Published Thursday, October 01, 2026 at 11:53 AM PT BLUF: Cisco Catalyst SD-WAN Manager is vulnerable to an unauthenticated remote admin access bypass (CVE-2026-76504). Attackers are exploiting this actively in the wild. Patch immediately if you operate SD-WAN deployments. Cisco has released fixes. DETAILS Vulnerability: Improper authentication check in Cisco Catalyst SD-WAN Manager allows remote attackers to access the platform without valid credentials—bypassing authentication entirely to gain administrative privileges. Active Exploitation: Multiple security vendors confirm this zero-day is being exploited in active attacks. The vulnerability is no longer theoretical; threat actors have proof-of-concept working code. Affected Product: Cisco Catalyst SD-WAN Manager, the centralized management and orchestration platform for software-defined WAN (SD-WAN) deployments across enterprise networks. Patch Status: Cisco has released patches and issued a security advisory. Patches are available; deployment timeline unclear from public disclosures. Attack Surface: Network-accessible; no user interaction required. Any instance of SD-WAN Manager exposed to an attacker-controlled network is at immediate risk. IMPACT ...
