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 是一个自托管的基于 Web 的文件管理器，支持多文件上传、编辑和批量操作。从版本 3.9.0 到 3.22.0，在未设置 PERSISTENT_TOKENS_KEY 或 metadata/persistent_tokens.key 的全新手动安装过程中，系统可能会激活一个已发布的旧版兼容密钥。如果攻击者单独获取了包含密文的账户文件或配置文件，则可以利用这个已知的 fallback 密钥解密 TOTP（基于时间的一次性密码）密钥或用户凭据。对于通过 Docker 进行的安装，系统会自动生成唯一的持久

Vulnerability Title
FileRise: Insecure default cryptographic key fallback in manual installs
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. From 3.9.0 until 3.22.0, pristine manual FileRise installations without PERSISTENT_TOKENS_KEY or metadata/persistent_tokens.key can activate a published legacy compatibility key. If an attacker separately obtains ciphertext-bearing account or configuration files, the known fallback key can enable decryption of TOTP secrets or credentials. Docker installations already generated a unique persistent key, and existing installations are not automatically rotated because doing so could make encrypted state unreadable. This issue is fixed in version 3.22.0.
