## Technical details

A stored XSS vulnerability exists due to insufficient output encoding of the MISP.org organization name setting when interpolated into a JavaScript string literal without escaping. An attacker with permission to set the organization name can inject arbitrary JavaScript using quote or backslash characters to break out of the string context. The injected payload executes in the browser of any authenticated user who subsequently loads the admin email composition page.
