What is CVE-2026-44775?
CVE-2026-44775 is a medium-severity missing authorization vulnerability in Kareadita Kavita, published on 26 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-306
