Alert meAnalysisAIv1 – Mar 12, 2026
Stored XSS in Cisco Prime Infrastructure and EPNM web management interfaces allows authenticated administrators with high privileges to inject malicious scripts that execute in other users' browsers, potentially enabling session hijacking or credential theft. The vulnerability stems from insufficient input validation in specific data fields and requires valid admin credentials to exploit. No patch is currently available.

DescriptionCVE.org
A vulnerability in the web-based management interface of Cisco Evolved Programmable Network Manager (EPNM) and Cisco Prime Infrastructure could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against users of the interface of an affected system.
This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by inserting malicious code into specific data fields in the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. To exploit this vulnerability, an attacker must have valid administrative credentials.
Executive ViewAI
CVE-2026-20075 presents moderate security risk, a cross-site scripting vulnerability rated CVSS 4.8. Attackers could inject scripts to steal sessions or perform actions as authenticated users. Organizations should apply vendor updates when available and monitor for exploitation.
Apply vendor patch. If patching is delayed: implement CSP headers, enable HttpOnly cookies, deploy WAF XSS rules.
