      "value": "Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to 1.19.0, the unauthenticated GET /api/app-images/logo endpoint reflects a user-supplied color query parameter into the body of an SVG document via strings.ReplaceAll with no escaping. The substitution lands inside a <style> element of the embedded logo.svg, allowing an attacker to close the style block and inject executable <script> content. Because the response is served as image/svg+xml and Arcane sets no Content-Security-Policy or X-Content-Type-Options headers, navigating a logged-in admin victim to a crafted URL executes attacker-controlled JavaScript in Arcane's origin and rides the victim's HttpOnly JWT cookie to fully compromise the admin account. This vulnerability is fixed in 1.19.0."

      "value": "Arcane es una interfaz para gestionar contenedores, imágenes, redes y volúmenes de Docker. Antes de la 1.19.0, el endpoint GET /api/app-images/logo no autenticado refleja un parámetro de consulta de color proporcionado por el usuario en el cuerpo de un documento SVG a través de strings.ReplaceAll sin escape. La sustitución aterriza dentro de un elemento [style] del logo.svg incrustado, permitiendo a un atacante cerrar el bloque de estilo e inyectar contenido [script_tag] ejecutable. Debido a que la respuesta se sirve como image/svg+xml y Arcane no establece encabezados Content-Security-Policy o X-Content-Type-Options, navegar a una víctima administradora con sesión iniciada a una URL manipulada ejecuta JavaScript controlado por el atacante en el origen de Arcane y aprovecha la cookie JWT HttpOnly de la víctima para comprometer completamente la cuenta de administrador. Esta vulnerabilidad se corrige en la 1.19.0."
