DescriptionCVE.org

A vulnerability was found in ChrisChinchilla Vale-MCP up to 0.1.0. Affected by this vulnerability is an unknown functionality of the file src/index.ts of the component HTTP Interface. The manipulation of the argument config_path results in os command injection. Attacking locally is a requirement. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

Local command injection in ChrisChinchilla Vale-MCP up to version 0.1.0 allows authenticated local attackers to execute arbitrary OS commands via manipulation of the config_path argument in the HTTP Interface component (src/index.ts). The vulnerability requires local access and valid user privileges, with publicly available exploit code disclosed after vendor non-response, representing a moderate-risk issue in environments where the MCP tool is deployed with local user access.

Vulnerability AssessmentAI

Risk Assessment	The CVSS 3.1 score of 5.3 reflects a local-only attack vector (AV:L) with low complexity (AC:L), requiring low privileges (PR:L) and user interaction absent (UI:N), with confidentiality, integrity, and availability all partially impacted (C:L/I:L/A:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	A local user with low privileges on a system running Vale-MCP accesses the HTTP Interface and crafts a request with a malicious config_path parameter containing shell metacharacters (e.g., config_path=$(whoami) or config_path=../../etc/passwd; cat). The unsanitized input is concatenated into an OS command execution call, allowing the attacker to execute arbitrary commands with the privileges of the Vale-MCP process. …
Remediation	No vendor-released patched version has been independently confirmed from the available data. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
