CVE-2026-77427 error311 CVE debrief
CVE-2026-77427 debrief: FileRise insecure default cryptographic key fallback allows decryption of secrets in manual installs. The vulnerability exists in FileRise manual installations from version 3.9.0 to 3.22.0, where a legacy compatibility key is used, allowing decryption of TOTP secrets or credentials if an attacker obtains ciphertext-bearing account or configuration files. Docker installations are not affected as they generate a unique persistent key. Existing installations do not have their encrypted state automatically rotated to avoid making it unreadable. Defenders should assess exposure, verify version and configuration, and upgrade to version 3.22.0 to fix the issue.
