Technical details
The vulnerability exists in the histogram.ctp template where the $selectedTypes variable derived from the URL path is directly interpolated into a JavaScript array literal within an onClick HTML attribute without encoding or escaping. An attacker crafts a malicious URL with a specially-crafted type value and socially engineers an authenticated MISP user to click it, causing arbitrary JavaScript execution in the victim's browser context with access to the MISP origin.
