CVE-2026-20294: Cleartext Transmission of Sensitive Information in Cisco Cisco Catalyst SD-WAN Manager
Severity: mediumType: VulnerabilityCVE-2026-20294
A vulnerability in the web-based management interface of Cisco Catalyst SD-WAN Manager could allow an authenticated, remote attacker to view sensitive information in clear text on an affected system. This vulnerability is due to insufficient access control enforcement for specific template types that are not included in the encryption allowlist. A low-privileged attacker could exploit this vulnerability by viewing logs on the local system or on a remote logging server. A successful exploit could allow the attacker to view sensitive authentication credentials, which could lead to further compromise of network infrastructure and connected services.
