CVE-2026-31862 is an OS command injection vulnerability (CWE-78) in Cloud CLI, also known as Claude Code UI, a desktop and mobile user interface for Claude Code, Cursor CLI, Codex, and Gemini-CLI. Published on 2026-03-11, it affects versions prior to 1.24.0, where multiple Git-related API endpoints invoke execAsync() using string interpolation of user-controlled parameters including file, branch, message, and commit names. This flaw enables attackers to inject and execute arbitrary operating system commands.
The vulnerability carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H), indicating exploitation is possible over the network with low complexity, no user interaction, and high privileges required, but with a changed scope leading to high impacts on confidentiality, integrity, and availability. Authenticated attackers with sufficient privileges can supply malicious payloads via the affected parameters to the API endpoints, achieving remote arbitrary command execution on the host system running the UI.
The issue is addressed in Cloud CLI version 1.24.0. Official mitigation involves updating to this patched release, as detailed in the GitHub security advisory (GHSA-f2fc-vc88-6w7q) and release notes (v1.24.0).

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
