# CVE-2026-57493: FileRise: Remember-me auto-login uses stale admin role from token instead of current role

- Also known as: GHSA-R55G-3HCC-6JX7
- Severity: CVSS 6.8 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 3.16.0

## Affected

- error311 FileRise: fixed in 3.16.0

## Description

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.
