Summary
CVE-2026-31862 affects Cloud CLI (aka Claude Code UI), a desktop and mobile UI for Claude Code, Cursor CLI, Codex, and Gemini-CLI, prior to 1.24.0. Multiple Git-related API endpoints pass user-controlled parameters (file, branch, message, commit) into execAsync() through string interpolation, which lets an authenticated attacker execute arbitrary OS commands. The weakness is classified as CWE-78 (OS Command Injection).
Mitigation
Fixed in 1.24.0.
