Short explanation
An authentication bypass vulnerability in FileRise allows attackers to obtain sessions for any account, including administrators, without a password or MFA due to missing source IP validation in reverse-proxy header trust.
The authentication bypass vulnerability enables unauthorized remote attackers to gain account access on FileRise deployments configured with proxy-header authentication.
What should be done?
- Update FileRise following vendor advisories
- Review reverse proxy and source IP validation settings
- Restrict direct external access to backend ports
Chain of evidence and sources
FileRise 3.16.0 öncesi sürümlerde AUTH_BYPASS etkinleştirildiğinde kaynak IP doğrulaması yapılmaz.

Show the technical text from the sources
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.
