Detailsinfo

A vulnerability, which was classified as critical, was found in knrdl Hubleys up to 0.5.1. This affects an unknown functionality. The manipulation with an unknown input leads to a unrestricted upload vulnerability. CWE is classifying the issue as CWE-434. The product allows the upload or transfer of dangerous file types that are automatically processed within its environment. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Hubleys is a dashboard for self-hosted services. Prior to version 0.5.2, any authenticated (non-admin) Hubleys user can upload a file with an arbitrary extension as their dashboard "background image," and the server will later serve that file back with a Content-Type derived straight from the attacker's chosen extension - so uploading an .html file gets it served as text/html. Because the endpoint that serves it returns a manually-constructed response rather than going through SvelteKit's normal page-rendering pipeline, the app's configured Content-Security-Policy never gets attached to it either, so a script embedded in the upload runs unrestricted. This issue has been patched in version 0.5.2.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-67444 since 07/29/2026. The exploitability is told to be easy.
