CVE-2026-77427
MEDIUM 5.9FileRise 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.
No known exploitation, public exploit, or elevated probability at this time. Track for changes.
