CVE-2026-31862 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. Cloud CLI (aka Claude Code UI) is a desktop and mobile UI for Claude Code, Cursor CLI, Codex, and Gemini-CLI. Prior to 1.24.0, multiple Git-related API endpoints use execAsync() with string interpolation of user-controlled parameters (file, branch, message, commit), allowing authenticated attackers to execute arbitrary OS commands. EPSS estimates a 0.44% chance of exploitation in the next 30 days.
