CVE-2026-95661
MISP contains a reflected cross-site scripting (XSS) vulnerability in the attribute histogram view.
Overview
CVE-2026-95661 is a known-severity vulnerability. It was published on September 22, 2026.
Technical description
MISP contains a reflected cross-site scripting (XSS) vulnerability in the attribute histogram view. The $selectedTypes variable, which is derived from the URL path segment , was interpolated directly into a JavaScript array literal inside an onClick HTML attribute without any encoding or escaping. An attacker who can cause an authenticated MISP user to visit a crafted URL containing a malicious type value can execute arbitrary JavaScript in the victim's browser within the MISP application origin.
Successful exploitation allows the attacker to read session cookies, perform actions on behalf of the victim, or exfiltrate sensitive data accessible from the MISP interface.
The vulnerability requires the victim to be authenticated and to actively navigate to the attacker-supplied URL.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
