CVE-2026-55477: CWE-73: External Control of File Name or Path in MHSanaei 3x-ui
3X-UI is a web control panel for managing Xray-core servers. Prior to 3.3.1, an authenticated administrator can abuse the database import functionality to achieve arbitrary file write on the host by modifying Xray configuration values stored in the database.
