CVE-2026-103977

Description

FileRise is a self-hosted web-based file manager with multi-file upload, editing, and batch operations. Prior to 3.23.0, FileRise stores failed TOTP verification attempts in $_SESSION. An attacker who already possesses a target account's valid primary credential can restart the login workflow in a new session and restore the second-factor attempt allowance, permitting continued online TOTP guessing beyond the intended five-attempt limit. The pending-login TOTP handlers did not share a durable account-wide limit. This issue is fixed in version 3.23.0.
