CVE-2026-31975

Cloud CLI (aka Claude Code UI) is a desktop and mobile UI for Claude Code, Cursor CLI, Codex, and Gemini-CLI. Prior to 1.25.0, OS Command Injection via WebSocket Shell. Both projectPath and initialCommand in server/index.js are taken directly from the WebSocket message payload and interpolated into a bash command string without any sanitization, enabling arbitrary OS command execution. A secondary injection vector exists via unsanitized sessionId. This vulnerability is fixed in 1.25.0.
