CVE-2026-44775

Kavita is a cross platform reading server. Prior to 0.9.0, the ReaderController.GetImage endpoint is decorated with [AllowAnonymous], allowing completely unauthenticated access to page images from any chapter in any library. While the endpoint accepts an apiKey parameter, it is never validated. Since entity IDs are sequential integers, an unauthenticated attacker can trivially enumerate all content on the server. This vulnerability is fixed in 0.9.0.

Summary		(es) Kavita es un servidor de lectura multiplataforma. Antes de la versión 0.9.0, el endpoint ReaderController.GetImage está decorado con [AllowAnonymous], permitiendo acceso completamente no autenticado a las imágenes de página de cualquier capítulo en cualquier biblioteca. Aunque el endpoint acepta un parámetro apiKey, nunca se valida. Dado que los ID de entidad son enteros secuenciales, un atacante no autenticado puede enumerar trivialmente todo el contenido en el servidor. Esta vulnerabilidad se corrige en la versión 0.9.0.
