VOC洞察专家

• Outcome: Review
• Latest audit: Sep 16, 2026 · 11:07 AM UTC
• Version: 1.0.2

Overview

The skill mostly matches Amazon VOC analysis, but it also adds broad LinkFox automation, silent feedback reporting, public upload, scheduling, and credential-bearing network calls that need review before use.

Install only if you trust LinkFox with your Amazon research context and API key. Before use, avoid setting custom gateway environment variables, do not upload private files unless you intend them to become publicly accessible, review any scheduled task before enabling it, and disable or block automatic feedback submission if possible.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• 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
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

Finding

The script builds outbound requests using a base URL taken from the LINKFOX_TOOL_GATEWAY environment variable and includes sensitive headers such as the API key plus session/message/app identifiers. If an attacker can influence that environment variable, requests and credentials can be redirected to an attacker-controlled endpoint, causing credential exfiltration and metadata leakage.

• Category: Data Flow
• Confidence: 95% confidence

Finding

The script builds outbound request destinations from environment-controlled base URLs and then sends sensitive data such as phone numbers, SMS codes, access tokens, refresh tokens, API keys, and user identifiers to those endpoints. If an attacker can influence the environment, they can redirect these requests to attacker-controlled infrastructure and exfiltrate credentials or payment-related data; this is especially dangerous because the file performs authentication and token issuance, not just low-risk telemetry.

Critical

• Category: Data Flow
• Confidence: 95% confidence

Finding

The gateway request path uses an environment-derived base URL and attaches the authorization header from LINKFOX_AGENT_API_KEY before calling urlopen. A compromised runtime environment could silently redirect authenticated requests to an attacker endpoint, exposing bearer credentials and enabling unauthorized account, order, or billing actions.

• Category: Data Flow

Finding

The script sends environment-derived values, including SESSION_ID, MESSAGE_ID, MODE_ID, APP_NAME, and an API key, to a remote endpoint whose base URL can itself be overridden by the LINKFOX_TOOL_GATEWAY environment variable. In an agent/runtime context where environment variables may be influenced by surrounding infrastructure or untrusted configuration, this creates a credible SSRF/exfiltration path: sensitive identifiers and request data can be forwarded to an attacker-controlled server without additional validation.

Finding

The script constructs request destinations from environment-controlled base URLs and then sends authentication material, including access tokens and API keys, to those endpoints via requests.post. If an attacker can influence the environment, they can redirect login or token-generation traffic to attacker-controlled infrastructure and capture credentials or induce SSRF-like outbound requests.

The script allows network destinations to be controlled by environment variables such as LINKFOX_LOGIN_API_URL and LINKFOX_AGENT_USER_API_URL, then sends sensitive data including phone numbers, SMS codes, access tokens, refresh tokens, and generated API keys to those endpoints.

Finding

download_media() performs outbound requests to arbitrary caller-supplied HTTP/HTTPS URLs with no host allowlist, no IP/range blocking, and no redirect validation. In an agent/runtime context this is a classic SSRF primitive that can be used to reach internal services, cloud metadata endpoints, or attacker-controlled infrastructure and store retrieved content locally.

Critical

• Category: Data Flow
• Confidence: 94% confidence

Finding

The download_media function performs arbitrary outbound HTTP(S) requests to a caller-supplied URL and writes the response into the workspace. That creates an SSRF-style primitive and enables retrieval of untrusted remote content without allowlisting, destination validation, or purpose limitation, which is especially risky because this skill's stated VOC analysis role does not require general network downloading.

• Category: Data Flow

Finding

The request destination and multiple outbound headers are influenced by environment variables, especially LINKFOX_TOOL_GATEWAY and session/app identifiers, and then sent via urlopen without validation. In an agent/runtime setting, a malicious or compromised environment can redirect requests to an attacker-controlled host and exfiltrate API keys and session metadata through the Authorization and custom headers.

The POST target URL is derived from environment-controlled base URLs, and this function sends sensitive authentication material such as access tokens, refresh tokens, phone numbers, SMS codes, and generated API tokens to that destination. If an attacker can influence environment variables or skill configuration, they can redirect requests to attacker-controlled infrastructure and exfiltrate credentials through a feature that appears to be normal onboarding.

The code builds request destinations from environment variables such as LINKFOX_LOGIN_API_URL and LINKFOX_AGENT_USER_API_URL, then sends sensitive data including phone numbers, SMS codes, access tokens, refresh tokens, and generated API keys to those URLs.

Finding

The media downloader accepts an arbitrary caller-supplied URL and fetches it over the network with no allowlist, host validation, or private-address blocking. In an agent environment this can be abused for SSRF, letting an attacker trigger requests to internal services, cloud metadata endpoints, or other restricted network locations, and then persist the fetched content locally.
