Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
FileRise 是一款自托管的基于 Web 的文件管理器，支持多文件上传、编辑和批量操作。在 3.16.0 版本之前，FileRise 将 isAdmin 标志存储在“记住我”（remember-me）令牌中，并在自动登录时恢复该过时值，而不是从 users.txt 中解析账户的当前角色。若用户在担任管理员期间被授予令牌，则在降权后仍可保留管理员访问权限；此外，令牌轮换过程会将该过时的权限复制到每个替换令牌中。要利用此漏洞，攻击者需持有降权前的“记住我”令牌。该问题已在 3.16.0 版本中修复。

Vulnerability Title
FileRise: Remember-me auto-login uses stale admin role from token instead of current role
Source: CVE Program / CVE List V5
Vulnerability 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.
