FKIE_CVE-2026-57493

Vulnerability from fkie_nvd - Published: 2026-10-14 21:17 - Updated: 2026-10-20 03:17
Severity
6.8 (Medium) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N
Summary
FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.16.0, FileRise stores the isAdmin flag in remember-me tokens and restores that stale value during automatic login instead of resolving the account's current role from users.txt. A user who was issued a token while an administrator can retain administrator access after demotion, and token rotation copies the stale privilege into each replacement token. Exploitation requires possession of the pre-demotion remember-me token. This issue is fixed in version 3.16.0.
