What is CVE-2026-20169?

A vulnerability within the web-based management interface of Cisco IoT Field Network Director allows an authenticated remote attacker with limited privileges to access sensitive files and execute commands on a remote router. This issue stems from inadequate input validation of user-supplied data, making it possible for an attacker to exploit the vulnerability by entering specially crafted input via the management interface.
