## What is CVE-2026-104106?

CVE-2026-104106 is a medium-severity vulnerability in error311 FileRise, published on 14 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.23.0, FileRise permits an authenticated session with a valid CSRF token to disable TOTP without recent full reauthentication or to begin enrollment when the account currently has no TOTP secret. The enrollment endpoint returns 409 rather than directly overwriting an already configured secret, but it persists and activates a newly generated secret before a TOTP code verifies possession. An attacker controlling an existing authenticated session can therefore disable an existing second factor or enroll one after the account has no configured secret; this is not a direct overwrite of an active authenticator. This issue is fixed in version 3.23.0.

Weakness: CWE-620 (Unverified Password Change), CWE-306 (Missing Authentication for Critical Functionality)
