CVE-2026-104106— FileRise: 2FA disable and TOTP enrollment lack step-up re-authentication; enrollment activates before verification

Quick assessment

Affected
error311 FileRise
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
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 3.23.0 版本之前，FileRise 允许使用有效的 CSRF 令牌和已认证会话来禁用 TOTP（基于时间的一次性密码算法），或在当前账户未配置 TOTP 密钥的情况下开始注册。注册接口返回 HTTP 409 状态码，而不是直接覆盖已配置的密钥，但它会在验证 TOTP 代码以确认拥有权之前，先持久化并激活新生成的密钥。因此，攻击者若控制一个已认证的会话，可以禁用现有的第二因素认证，或在账户未配置密钥时注册新的 TOT

Vulnerability Title
FileRise: 2FA disable and TOTP enrollment lack step-up re-authentication; enrollment activates before verification
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 3.23.0, FileRise permits an authenticated session with a valid CSRF token to disable TOTP without recent full reauthentication or to begin enrollment when the account currently has no TOTP secret. The enrollment endpoint returns 409 rather than directly overwriting an already configured secret, but it persists and activates a newly generated secret before a TOTP code verifies possession. An attacker controlling an existing authenticated session can therefore disable an existing second factor or enroll one after the account has no configured secret; this is not a direct overwrite of an active authenticator. This issue is fixed in version 3.23.0.
