   Cisco, 2026-09-30. Leer, 7 min.

   Cisco disclosed CVE-2026-76504 (CVSS 9.8), a flaw in the API authentication of Cisco Catalyst SD-WAN Manager that could let an unauthenticated, remote attacker access an affected system with the privileges of the admin user, and says its PSIRT became aware of active exploitation in September 2026. Fixed releases include 20.9.10.1, 20.12.8.2, 20.15.6.1, 20.18.4.1, 26.1.2.1 and 26.2.1, and the Cisco-managed cloud release 20.15.605 needs no customer action.

   Por qué importa para este rol: Schedule the SD-WAN Manager upgrade now, with a migration plan for any release earlier than 20.9, where Cisco offers no fixed build of its own.
