CVE-2026-33072

HIGH

FileRise: Default Encryption Key Enables Token Forgery and Config Decryption

Title source: cna
STIX 2.1

Description

FileRise is a self-hosted web file manager / WebDAV server. In versions prior to 3.9.0, a hardcoded default encryption key (default_please_change_this_key) is used for all cryptographic operations — HMAC token generation, AES config encryption, and session tokens — allowing any unauthenticated attacker to forge upload tokens for arbitrary file upload to shared folders, and to decrypt admin configuration secrets including OIDC client secrets and SMTP passwords. FileRise uses a single key (PERSISTENT_TOKENS_KEY) for all crypto operations. The default value default_please_change_this_key is hardcoded in two places and used unless the deployer explicitly overrides the environment variable. This issue is fixed in version 3.9.0.
