CVE-2026-123039 · Severity: high · CVSS 7.8 · Published 2026-11-12

Gaia OS includes a DynamicCLI daemon that runs with root privileges but accepts commands from any local user via an unprotected socket file. An attacker with local access to the system can send arbitrary commands to this socket and have them executed as root, gaining full control of the operating system.

## Technical details

The DynamicCLI daemon listens on a world-writable Unix socket (/tmp/dynamic_socket) without authenticating connecting processes. A local attacker can connect to this socket and execute commands that are processed with root privileges. This is a local privilege escalation vulnerability requiring only local system access.
