"The version of Cisco Catalyst Center (formerly Cisco DNA Center) installed on the remote host is affected by a
vulnerability.

  - A vulnerability in Cisco Catalyst Center could allow an unauthenticated, remote attacker to read
    arbitrary files from a restricted container. This vulnerability is due to insufficient validation of
    user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request to
    an affected device. A successful exploit could allow the attacker to read arbitrary files from a
    restricted container of the affected device. (CVE-2026-20191)
