CVE-2026-55477 HIGH PATCH This Week

Arbitrary file write in 3X-UI, a web control panel for managing Xray-core proxy servers, allows an authenticated administrator to write attacker-controlled files anywhere on the host by tampering with Xray configuration values through the database import feature in versions prior to 3.3.1. Because the written files execute in the context of the Xray process - frequently root in self-hosted deployments - this escalates to full code execution and persistent host compromise. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; it is resolved in release 3.3.1.
