What is CVE-2026-33072?

FileRise, a self-hosted web file manager and WebDAV server, suffers from a serious vulnerability in its implementations prior to version 3.9.0. It utilizes a hardcoded default encryption key, which is employed across various cryptographic processes, including HMAC token generation, AES configuration encryption, and session token management. This design oversight permits unauthenticated attackers to forge upload tokens for arbitrary file uploads to shared directories and to decrypt sensitive administrative configuration secrets, including OIDC client details and SMTP credentials. The issue has been resolved in version 3.9.0, urging users to update to mitigate the risk.

Affected Version(s)
