Title
Chevereto before 4.5.8 Private Album Image Disclosure via get-album-contents
Summary
Chevereto before 4.5.8 contains an authorization bypass vulnerability in the get-album-contents action of the /json route that allows unauthenticated attackers to list private albums by supplying another user's album id. Attackers with a session token from any public page and an album's encoded id can obtain image filenames, viewer and direct file URLs, and download private images.

Title
Chevereto private profile setting leaks username on /json endpoint
Summary
Chevereto is a self-hosted media-sharing platform. Starting in version 3.7.5 and prior to version 4.5.4, when a user enables the private profile option, visiting their profile HTML route (`/username`) correctly returns 404. However, the `/json` AJAX listing endpoint does not apply the same check. An unauthenticated caller who knows the target's user ID can retrieve all of that user's publicly-scoped images, revealing the username (which should be private). This is patched in Chevereto v4.5.4. No known workarounds are available.
