Description

FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.16.0, FileRise deployments with AUTH_BYPASS enabled trust the configured reverse-proxy identity header without verifying that the request originated from FR_TRUSTED_PROXIES. When the backend application port is reachable directly, an unauthenticated attacker can supply X-Remote-User and obtain a session for the asserted account, including an administrator account, without a password or MFA. The flaw is limited to deployments that enable proxy-header authentication and expose an untrusted path to the backend. This issue is fixed in version 3.16.0.
