CVE-2026-44460: FileRise: TOTP Bypass via Setup Endpoint Disclosing Existing Secret

FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.12.0, /api/totpsetup.php is callable from a session that has only passed the password check (state pendingloginuser). When the target account already has TOTP configured, the endpoint decrypts and returns the user's existing TOTP secret inside the QR PNG instead of refusing or generating a new secret. An attacker who already possesses the victim's password can therefore retrieve the live TOTP secret, derive a valid one-time code, submit it to /api/totpverify.php, and obtain a fully authenticated session without ever possessing the victim's authenticator device. This vulnerability is fixed in 3.12.0.
