Overview

The skill can perform TikTok product lookups, but it also adds account, billing, automatic feedback sharing, and broad local persistence behaviors that need review before installation.

Review this before installing if you are comfortable with LinkFox account, billing, and feedback workflows living inside a product lookup skill. Use a dedicated API key, verify LINKFOX_* endpoint environment variables are not overridden, avoid sharing phone verification codes through the agent unless necessary, confirm any paid order manually, and delete local linkfox output/cache files when they are no longer needed.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Insecure Dependencies: Introduces malicious components through unsafe dependency sources
• 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

dict: try: import qrcode except ImportError: err = "Missing qrcode dependency; run: pip install qrcode pillow" print(f"{TAG} render_qr: {err}", file=sys.stderr) return {"png_path": None, "ascii_qr": None, "error": err} ``` It gives equivalent unpinned installation guidance for the HTTP dependency: ```python def _require_requests() -> None: if requests is None: raise RuntimeError("Missing requests dependency; run: pip install requests") ``` ### Technical Analysis The project has no reviewed dependency lockfile, exact version constraints, or package hashes. Users are instructed to install the latest mutable releases and their transitive dependencies directly from the configured Python package index. These packages execute within the onboarding process, which handles: - Phone numbers. - SMS verification codes. - Access and refresh tokens. - Generated API keys. - Payment URLs and QR content. - Account and order details. Although no specific malicious package is embedded in the audited project, the installation procedure unnecessarily exposes a sensitive authentication and payment flow to package-index compromise, dependency substitution, unexpected upstream changes, and compromised transitive dependencies. ### Attack Path 1. The user invokes onboarding without `requests`, `qrcode`, or `Pillow` installed. 2. The script instructs the user to execute an unpinned `pip install`. 3. The package resolver retrieves the current package versions and transitive dependencies from the configured package source. 4. A compromised, substituted, or u ...[truncated 820 chars]

Tainted flow: 'req' from os.environ.get (line 71, credential/environment) → urllib.request.urlopen (network output)

Critical

• Category: Data Flow
• Confidence: 93% confidence

Finding

The request sent via urlopen includes multiple HTTP headers populated directly from environment variables, and the destination base URL is also controlled by LINKFOX_TOOL_GATEWAY. In an untrusted or attacker-influenced execution environment, this can exfiltrate sensitive workflow metadata and the API key to an attacker-controlled endpoint or enable SSRF-style outbound requests.

Tainted flow: 'req' from os.environ.get (line 71, credential/environment) → urllib.request.urlopen (network output)

Critical

• Category: Data Flow
• Confidence: 98% confidence

Finding

The request sent via urlopen includes multiple headers populated directly from environment variables, and the destination host is also overrideable via LINKFOX_TOOL_GATEWAY. In an agent/runtime context, this creates an exfiltration path where attacker-controlled environment values and the API key can be forwarded to an arbitrary remote endpoint if the gateway variable is manipulated.

Tainted flow: 'url' from os.environ.get (line 235, credential/environment) → requests.post (network output)

Critical

• Category: Data Flow
• Confidence: 95% confidence

Finding

The code builds destination URLs from environment-controlled base URLs and then sends sensitive authentication material to them via requests.post. Because this CLI handles SMS login, access tokens, refresh tokens, and API key generation, a tampered environment can redirect those secrets to an attacker-controlled endpoint, causing credential exfiltration and account compromise.

Tainted flow: 'req' from os.environ.get (line 244, credential/environment) → urllib.request.urlopen (network output)

Critical

• Category: Data Flow
• Confidence: 94% confidence

Finding

The gateway request path uses environment-derived base URLs and includes the API key in the Authorization header before calling urlopen. An attacker who can influence environment variables can redirect package, order, and account requests to a malicious server and harvest the API key or manipulate responses used by the CLI.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 99% confidence

Finding

The documented behavior goes far beyond TikTok product ranking/detail lookup and includes SMS-based login, token generation, account/team inspection, subscription listing, order creation, payment QR generation, and payment status polling. This is a serious scope-expansion issue because a user invoking a data lookup skill could unknowingly trigger authentication, billing, or account-management actions against a third-party service.

Content

Vague Triggers

High

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

Finding

The trigger conditions are broad enough to activate on generic product-detail or product-analytics intents, even when the user did not ask for Kalodata specifically. Overbroad triggering increases the chance of accidental invocation of a skill that performs persistence, external API calls, or other side effects the user did not intend.

Description-Behavior Mismatch

High

• Category: Not specified by scanner
• Confidence: 99% confidence

Finding

This file implements SMS login, API key issuance, subscription discovery, order creation, payment QR rendering, and order-status checks, which are materially unrelated to the declared TikTok product-ranking/query functionality. In skill context, this mismatch is dangerous because it expands the capability from read-only analytics into account onboarding and monetization flows that can collect credentials and trigger commercial actions.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The code can create orders and generate payment QR codes, introducing write-side financial actions into a skill presented as a data lookup tool. That capability mismatch increases the chance of deceptive or unintended purchases, especially if an agent invokes the skill based on product-ranking requests rather than explicit payment intent.

Content

No source excerpt is available for this finding.

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 96% confidence

Finding

The skill declares no explicit tool scope even though it clearly uses environment variables, network access, and file writes. Missing least-privilege boundaries makes it easier for the skill to perform unreviewed side effects such as local persistence, API calls, or account-related flows beyond the user's expected product lookup request.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The skill states that full API responses are always written to a local session-linked path, but this persistence is not presented as a clear up-front user warning or optional behavior. Users asking for a simple lookup may not expect their query parameters and returned data to be stored on disk in the project directory.

Content

No source excerpt is available for this finding.

Ssd 3

Medium

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

Finding

Requiring storage of every full API response under a session-linked directory creates unnecessary retention of potentially sensitive or proprietary data and links it to a session identifier for later access. This increases exposure through accidental reuse, local compromise, multi-user environments, or later prompt/context inclusion beyond the immediate task.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

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

Finding

The skill instructs automatic submission of feedback to an external API whenever various conditions occur, including user praise, dissatisfaction, or anything improvable. That creates undisclosed outbound data sharing unrelated to the core product lookup purpose and may leak user content, preferences, or conversation-derived metadata without explicit consent.

Content

No source excerpt is available for this finding.

External Transmission

Medium

• Category: Data Exfiltration
• Confidence: 60% confidence

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Context-Inappropriate Capability

Medium

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

Finding

The documented Feedback API introduces a secondary capability unrelated to the skill's stated purpose of product ranking/detail lookup. This expands the skill's data flows and creates a path for transmitting user-derived content to a separate external service, which is risky because it may be invoked without clear user awareness or necessity for the requested task.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The Feedback API section instructs sending free-form 'content' describing what the user said or intended to an external endpoint, but provides no privacy notice, consent requirement, or restriction against including sensitive data. This creates a realistic risk of exfiltrating user prompts, preferences, or other confidential context to a third party without transparency.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

Medium

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

Finding

The onboarding guide materially expands the skill from TikTok product analytics into account recovery, phone-based registration, and billing purchase flows. This increases attack surface and creates opportunities for collection of credentials, phone numbers, and payment interactions unrelated to the declared skill purpose, violating least privilege and making social-engineering abuse easier.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The guide instructs the operator to handle a user's phone number and one-time verification code in order to register or log in through a script, even though this is unnecessary for a product-ranking skill. Handling OTPs and phone-based login data creates a sensitive credential collection path that can be abused for account takeover or unauthorized account creation.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

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

Finding

The document instructs use of a script that processes phone numbers and login codes, then persists an API key into shell profile files, but it provides no warning about sensitive data handling, credential secrecy, or the permanence of modifying user environment configuration. This can lead to accidental exposure of personal data and long-lived credentials, and may leave users unaware that they are making persistent system changes.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

Medium

• Category: Not specified by scanner
• Confidence: 93% confidence

Finding

The billing flow directs the use of a script to list plans, create payment orders, and query order status, which is outside the stated analytics-only purpose of the skill. Mixing commerce and payment handling into an unrelated skill raises phishing and unauthorized purchase risk, especially if users are socially engineered into buying plans under the guise of normal product queries.

Content

No source excerpt is available for this finding.

Intent-Code Divergence

Medium

• Category: Not specified by scanner
• Confidence: 96% confidence

Finding

The module documentation promises that writing to /tmp is forbidden and that non-writable current directories should cause an error, but the implementation silently falls back to a temporary directory. This discrepancy can cause sensitive API responses to be stored in less-controlled transient locations, undermining operator expectations and potentially exposing data to other local processes or weakening data-governance guarantees.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

Medium

• Category: Not specified by scanner
• Confidence: 92% confidence

Finding

The script always persists full API responses and session metadata to local storage, despite the skill being described as a query tool for ranking/detail lookup. In an agent setting, silent archival of returned data can retain sensitive business data, identifiers, and usage metadata beyond the user's expectation, increasing disclosure risk.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

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

Finding

The script writes the full API response to disk on every run without explicit confirmation at execution time. In this skill context, product analytics responses and session metadata may be commercially sensitive, so unconditional persistence creates unnecessary retention and possible later exposure through local access, backups, or logs.

Content

No source excerpt is available for this finding.

Intent-Code Divergence

Medium

• Category: Not specified by scanner
• Confidence: 97% confidence

Finding

The top-level documentation explicitly says output is always written under <cwd>/linkfox/... and forbids /tmp, with an error if the current directory is not writable. However, _linkfox_root intentionally falls back to ~/linkfox and then $TMPDIR/linkfox, directly contradicting that documented behavior.
