Overview

This skill is purpose-aligned for VMware Aria Operations sustainability reporting, but it sends an API token over HTTPS with certificate checks disabled and can return fabricated-looking report data after live API failures.

Review before installing. Use only a least-privilege, read-only Aria Operations token; do not run this version on an untrusted network; require proper TLS certificate validation or a trusted CA bundle; and treat simulated fallback metrics as unsafe for reporting unless mock mode is explicitly controlled. 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

This includes authentication failures, authorization failures, missing endpoints, rate limits, and server errors. Although the output contains a parenthetical statement identifying the payload as simulated, it is returned by a tool whose stated purpose is to retrieve organizational sustainability metrics. Automated agents or downstream reporting systems may extract the numerical fields without preserving or recognizing that disclaimer. The implementation therefore fails open with plausible fabricated data rather than clearly signaling that live data retrieval failed. It also discards the ...[truncated 1118 chars]

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Tool Misuse: Tool Parameter Abuse, Chaining Abuse, Unsafe Defaults
• Taint Tracking: Direct Taint Flow, Variable-Mediated Taint Flow, Credential Exfiltration Chain
• MCP Least Privilege: Underdeclared Capability, Wildcard Permission, Missing Permission Declaration

Findings (9)

Tainted flow: 'url' from os.getenv (line 25, credential/environment) → requests.get (network output)

Critical

• Category: Data Flow
• Confidence: 90% confidence

Finding

Credentials or environment variables flow to a network sink. This is a high-confidence indicator of credential exfiltration.

Undeclared Tool Scope

Medium

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

Finding

The skill requires sensitive environment variables and network access but does not declare any explicit tool scope or permission boundaries. That weakens least-privilege controls and makes it easier for an agent or operator to run the skill with broader capabilities than intended, increasing the chance of unauthorized external access or misuse of the API token.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The documentation tells users to configure an API token and connect to VMware Aria Operations but does not clearly warn that the skill will access sensitive organizational sustainability and ESG-related data. This can lead to uninformed deployment, accidental exposure of business-sensitive metrics, and poor token-handling practices by operators who are not made aware of the data sensitivity.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 90% confidence

Finding

This tool silently uses a credential from the environment to make a network request to an external service without any user-facing disclosure or confirmation. In an MCP/agent context, that can cause users or orchestrators to invoke the tool without realizing it will transmit privileged credentials and query infrastructure data, increasing the chance of unintended data access or privacy/compliance issues.

Content

No source excerpt is available for this finding.

Unsafe Defaults

Medium

• Category: Tool Misuse
• Confidence: 98% confidence

Finding

The request disables TLS certificate verification with verify=False, and the code also suppresses the corresponding warnings globally. This permits man-in-the-middle interception or spoofing of the Aria Operations endpoint, which is especially dangerous because the request carries an API token and retrieves potentially sensitive sustainability and infrastructure data.

Unpinned Dependencies

Low

• Category: Supply Chain
• Confidence: 97% confidence

Finding

The dependency mcp is unpinned, which makes builds non-reproducible and can cause the skill to install different versions over time, including versions with known security defects. In an MCP server context, this is more concerning because mcp is a core protocol/runtime dependency and vulnerable releases could directly affect server-side request handling or client trust boundaries.

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: 94% confidence

Finding

mcp has known advisories, and because no version is specified, there is no way to verify that the installed package is not one of the vulnerable releases. This is more dangerous here than in a generic utility because the package underpins an MCP server, so issues such as validation flaws, DNS rebinding weaknesses, or task-access problems could directly expose the service to remote abuse.

Unpinned Dependencies

Low

• Category: Supply Chain
• Confidence: 96% confidence

Finding

The dependency requests is unpinned, so deployments may resolve to different versions with different security properties, including releases affected by known CVEs. Because this skill interfaces with external services, an insecure or unexpectedly changed HTTP client library could expose credentials, weaken TLS-related behavior, or alter request handling in ways that affect confidentiality and integrity.

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: 93% confidence

Finding

requests has multiple published advisories, and leaving it unpinned makes it impossible to confirm whether the deployed version contains a credential leak, verification flaw, or other security issue. Since this skill communicates with VMware Aria Operations and may handle API endpoints and credentials, a vulnerable HTTP client could increase the risk of sensitive data exposure or unsafe outbound connections.
