CVE-2026-76433
Cisco Identity Services Engine Information Disclosure Vulnerability
A vulnerability in the client provisioning download feature of Cisco ISE and Cisco ISE-PIC could allow an unauthenticated, remote attacker to access protected files on an affected device.
This vulnerability is due to insufficient validation of directory traversal character sequences in a user-supplied path when the software processes provisioning resource requests. An attacker could exploit this vulnerability by sending a crafted request to the provisioning download service. A successful exploit could allow the attacker to access protected files without authentication, potentially exposing sensitive information.
