Cisco has confirmed that two Catalyst SD-WAN Manager vulnerabilities (CVE-2026-20128 and CVE-2026-20122) patched in late February 2025 are being exploited by attackers.
The exploited vulnerabilities (CVE-2026-20128, CVE-2026-20122)
CVE-2026-20128 is a bug in the Data Collection Agent (DCA) feature of Cisco Catalyst SD-WAN Manager, which could allow an authenticated, local attacker to gain DCA user privileges on an affected system.
