CVE-2026-76432
Last modified
CVE-2026-76432 is a medium-severity vulnerability rated 4.9/10 on the CVSS scale. A vulnerability in the web-based management interface of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker with administrative-level privileges to write arbitrary files on an affected device. This vulnerability exists because the affected software does not properly validate directory traversal character sequences in a user-supplied file path during the upload process. An attacker could exploit this vulnerability by uploading a crafted file to the affected system. EPSS estimates a 1.21% chance of exploitation in the next 30 days.
