CVE-2026-95665
MISP contains a reflected cross-site scripting (XSS) vulnerability in the event REST search export confirmation form.
Overview
CVE-2026-95665 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 event REST search export confirmation form. The view template app/View/Events/ajax/eventRestSearchExportConfirmationForm.ctp renders a URL-supplied event ID list into a single-quoted JavaScript string literal using PHP's json_encode() without any hex-encoding flags. By default, json_encode() escapes double quotes and backslashes but does not escape single quotes. Because the JavaScript string is delimited by single quotes, an attacker can inject a single-quote character to terminate the string literal and execute arbitrary JavaScript in the victim's browser session.
The vulnerability affects the Default and UiBeta themes, both of which render this view. The Overmind theme's own copy of the form already passed the value through an escaped data attribute and was not affected by this specific sink.
Preconditions: the victim must be an authenticated MISP user and must actively open or navigate to the attacker-craft
