CISA added CVE-2026-76461, a SQL injection flaw in the Cisco email security appliance, to its Known Exploited Vulnerabilities catalog on 2026-09-14. Federal agencies have until 2026-09-17 to apply vendor mitigations under BOD 26-04, with forensic triage required.
The flaw could let an unauthenticated remote attacker run arbitrary commands with root privileges on the underlying operating system.
It remains unknown whether the vulnerability is known to be used in ransomware campaigns.
Organizations running Cisco SEG should treat this as an immediate priority given confirmed active exploitation and the root-privilege impact.
