VCF Regulatory Compliance

• Outcome: Review
• Latest audit: Sep 16, 2026 · 5:08 AM UTC
• Version: 1.0.1

Overview

The skill’s main purpose is coherent, but it handles an infrastructure API token unsafely and can return simulated compliance findings when live checks fail.

Review before installing. Use only with a narrowly scoped read-only Aria Operations token, restrict the host to your intended internal endpoint, require real TLS certificate validation or a trusted CA bundle, and remove or gate the simulated-report fallback so failed API calls cannot produce fake compliance results. Pin dependencies before production use.

Vulnerability Patterns

• Insecure Dependencies: Introduces malicious components through unsafe dependency sources
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review

The response contains a simulated-payload note, but it otherwise has the form of a valid regulatory report and supplies specific remediation instructions. An agent or operator can therefore consume invented findings as though they describe the actual environment. The behavior also hides the real HTTP failure ...[truncated 1258 chars]

Findings (10)

Tainted flow: 'url' from os.getenv (line 34, credential/environment) → requests.get (network output)

Critical

• Category: Data Flow
• Confidence: 90% confidence

Finding

The request URL is built from the ARIA_OPS_HOST environment variable and sent with an API token, while TLS certificate validation is explicitly disabled. If an attacker can influence the host value or intercept traffic, they could redirect the request and capture the bearer token or sensitive compliance query data. In this skill’s context, the tool is explicitly intended to reach an internal VMware Aria Operations endpoint, so outbound requests to an attacker-controlled host are especially risky.

Description-Behavior Mismatch

High

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

The skill advertises live compliance checks against the VCF environment, but the fallback emits hard-coded findings unrelated to the actual deployment. This creates integrity risk: operators may make security decisions based on invented violations, or overlook real issues because the tool masks API failures with plausible output.

Content

No source excerpt is available for this finding.

Intent-Code Divergence

High

• Category: Not specified by scanner
• Confidence: 98% confidence

Finding

On any non-200 response, the tool returns a polished simulated compliance report that appears authoritative instead of clearly failing. This can mislead users into acting on fabricated security findings or falsely believing the environment was assessed, which is dangerous for a compliance-scanning skill where trust in result accuracy is essential.

Content

No source excerpt is available for this finding.

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 92% confidence

Finding

The skill declares and documents use of sensitive environment variables and network access, but does not define any explicit tool scope such as permissions or allowed-tools. That leaves the agent/runtime without a clear least-privilege boundary, increasing the chance the skill can access secrets or make unintended outbound requests beyond what reviewers expect. In this context, the skill connects to VMware Aria Operations using an API token, so unclear scoping is more dangerous because it involves privileged infrastructure and compliance data.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 94% confidence

Finding

This code reads a sensitive credential from ARIA_OPS_API_TOKEN and sends it in an HTTPS request header, but there is no user-facing print/log message, confirmation, or warning comment/docstring explaining that credentials and host data will be used for a live API call. The docstring describes the feature purpose, but it does not disclose the credential use or outbound transmission behavior.

Content

No source excerpt is available for this finding.

Unsafe Defaults

Medium

• Category: Tool Misuse
• Confidence: 99% confidence

Finding

The code disables TLS certificate verification and suppresses the corresponding warnings, allowing man-in-the-middle interception without visibility to the user. Because the request includes a sensitive Aria Operations API token and targets compliance data in an enterprise environment, this weak default materially increases the chance of credential theft and response tampering.

Unpinned Dependencies

Low

• Category: Supply Chain
• Confidence: 97% confidence

Finding

The dependency mcp is unpinned, so installs may resolve to different versions over time, including vulnerable or breaking releases. In an MCP server that interfaces with VMware Aria Operations and performs compliance checks, this increases supply-chain risk because a future install could silently pull a compromised or insecure SDK version into a security-sensitive integration.

requests

Unverifiable Dependency: mcp has 12 known advisory(ies) (CVE-2025-53366 (MCP Python SDK vulnerability in the FastMCP Server causes validation error, lead); CVE-2025-66416 (Model Context Protocol (MCP) Python SDK does not enable DNS rebinding protection); CVE-2026-52870 (MCP Python SDK: Experimental task handlers allow any client to access and cancel) +9 more), but the manifest does not pin a version, so it is unknown whether the installed release is affected

Low

• Category: Supply Chain
• Confidence: 95% confidence

Finding

mcp has multiple known advisories, and because no version is pinned, there is no way to verify whether deployment will use a fixed or vulnerable release. This is especially concerning in an MCP server context, where SDK flaws can affect server exposure, client access controls, or request validation in a component that may process sensitive compliance and infrastructure data.

Content

No source excerpt is available for this finding.

Unpinned Dependencies

Low

• Category: Supply Chain
• Confidence: 98% confidence

Finding

The dependency requests is also unpinned, which makes builds non-reproducible and can introduce vulnerable versions during installation. Because this skill likely makes outbound API calls to VMware Aria Operations, any weakness in the HTTP client library could directly affect authentication, credential handling, or transport security behavior.

requests

Unverifiable Dependency: requests has 16 known advisory(ies) (CVE-2014-1830 (Exposure of Sensitive Information to an Unauthorized Actor in Requests); CVE-2024-47081 (Requests vulnerable to .netrc credentials leak via malicious URLs); CVE-2024-35195 (Requests `Session` object does not verify requests after making first request wi) +13 more), but the manifest does not pin a version, so it is unknown whether the installed release is affected

Low

• Category: Supply Chain
• Confidence: 94% confidence

Finding

requests has many historical advisories, and without version pinning the actual installed package may be vulnerable. In a tool that communicates with infrastructure management endpoints, this uncertainty can expose secrets, mishandle redirects or URL parsing, or weaken secure request behavior depending on which version gets installed.
