DescriptionGitHub Advisory

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, The /api/user/git-config endpoint constructs shell commands by interpolating user-supplied gitName and gitEmail values into command strings passed to child_process.exec(). The input is placed within double quotes and only " is escaped, but backticks (`), $() command substitution, and \ sequences are all interpreted within double-quoted strings in bash. This allows authenticated attackers to execute arbitrary OS commands via the git configuration endpoint. This vulnerability is fixed in 1.24.0.

AnalysisAI

Arbitrary OS command execution in Cloud CLI versions prior to 1.24.0 allows authenticated users to inject malicious commands through improperly sanitized git configuration parameters passed to shell execution functions. The /api/user/git-config endpoint fails to properly escape bash metacharacters like backticks and $() substitutions, enabling attackers to execute arbitrary operating system commands with application privileges. No patch is currently available for affected deployments.
