CVE-2026-20349 HIGH POC KEV THREAT NEWS Act Now

Denial of service via crafted HTTP requests to the Remote Access SSL VPN service affects Cisco Secure Firewall ASA and FTD Software across a broad range of versions, enabling unauthenticated remote attackers to force an unexpected device reload and take down the firewall entirely. The Changed scope (S:C) in the CVSS vector reflects that the impact extends beyond the VPN process itself to the entire device, disrupting all traffic passing through it. This vulnerability is confirmed actively exploited (CISA KEV), with SSVC marking it as automatable, making it a high-priority remediation target for any organization with internet-exposed ASA or FTD VPN endpoints.
