Summary

CVE-2026-7066 is a medium-severity Command Injection (CWE-77) vulnerability. Its CVSS base score is 5.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 31% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

This vulnerability is AI-related — categorised as AI Agent Protocols and Integrations; in the Supply Chain and Deployment risk domain.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A vulnerability identified as CVE-2026-7066 affects the choieastsea simple-openstack-mcp project up to commit 767b2f4a8154cca344344b9725537a58399e6036. The issue resides in the exec_openstack function within server.py, where improper handling of input enables OS command injection, corresponding to CWE-77 and CWE-78. The product follows a rolling-release model, so no specific version numbers distinguish affected or fixed releases.

The flaw can be exploited remotely by unauthenticated attackers who supply crafted input to trigger arbitrary operating-system commands. A public exploit is already available, and the CVSS 4.0 score of 5.5 reflects limited impacts to confidentiality, integrity, and availability without requiring user interaction or privileges.

The project was notified of the problem through an issue report but has not issued a response or patch. Reference materials, including the GitHub repository and associated Vuldb entries, contain no mitigation guidance or updated code. The associated EPSS score has remained essentially flat between 0.0212 and a peak of 0.0218, indicating no notable increase in observed exploitation interest.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover command-construction flaws before deployment.

Input validation directly stops construction of commands from untrusted data containing special elements.

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 include proper neutralization and safe command construction practices.
