CVE-2026-77427: FileRise: Insecure default cryptographic key fallback in manual installs
Noroxi assessment
Priority: Monitor (action score 23/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.34% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
- Fixed version: error311 FileRise 3.22.0.
Low priority for now. Upgrade to error311 FileRise 3.22.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
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.
