CISA Adds Fortinet FortiMail Path-Traversal CVE to KEV Catalog
The binding remediation requirement stops at FCEB agencies; everyone else gets CISA's encouragement, not a mandate.
CISA added CVE-2026-104286, a Fortinet FortiMail path-traversal vulnerability, to the Known Exploited Vulnerabilities Catalog after evidence of active exploitation. Under BOD 26-04, the listing brings rapid-remediation prioritization for FCEB agencies when the asset is publicly exposed and grants total control after exploitation, with lower-risk work deferred. The directive binds only FCEB agencies; for contractors it's CISA's encouragement, not a requirement.
