CVE-2026-126758 · Severity: medium · CVSS 4.4 · Published 2026-11-11

Moonshot AI Kimi Code, a developer assistant tool, contains a vulnerability in its workspace directory configuration that allows a local user to manipulate directory settings through an untrusted configuration file. An attacker with local access could modify the additional_dir argument to cause the application to trust malicious input when making security decisions, potentially leading to unauthorized access to files or code execution within the workspace context.
