Summary

CVE-2025-6514 is a critical-severity OS Command Injection (CWE-78) vulnerability in Jfrog (inferred from references). Its CVSS base score is 9.6 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 0.5% 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 Protocol-Specific Risks 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.

CVE-2025-6514 is an OS command injection vulnerability (CWE-78) in mcp-remote that arises when the client processes a crafted authorization_endpoint response URL returned by an untrusted MCP server. The flaw received a CVSS 3.1 score of 9.6, reflecting network attack vector, low complexity, no required privileges, and high impact across confidentiality, integrity, and availability with changed scope.

An unauthenticated remote attacker can exploit the issue by hosting a malicious MCP server that supplies malicious input in the authorization_endpoint field; when a user connects to that server, the injected commands execute on the client system, enabling full remote code execution.

A patch addressing the command-injection vector was merged in commit 607b226a356cb61a239ffaba2fb3db1c9dea4bac of the mcp-remote repository, and JFrog has published detailed analysis and mitigation guidance.

The EPSS score rose to a peak of 0.1606 before settling at the current value of 0.1217, indicating measurable post-disclosure exploitation interest.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

SI-10 Information Input Validation good match

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

AC-6 Least Privilege partial match

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

CM-7 Least Functionality partial match

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match
prevents

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.

PR.PS-02 partial match
prevents

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).
