CVE-2026-20189

Cisco Prime Infrastructure Information Disclosure Vulnerability

Published May 6, 2026 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed

Description

A vulnerability in the log file download functionality of Cisco Prime Infrastructure could allow an authenticated, remote attacker to download arbitrary log files from the server.

This vulnerability is due to insufficient authorization checks on the download service API. An attacker could exploit this vulnerability by submitting a crafted URL request to an affected device. A successful exploit could allow the attacker to download sensitive log files that they would otherwise not have authorization to access.
To exploit this vulnerability, the attacker must have valid credentials to access the web-based management interface of the affected device.
