• Version: 1.0.6

Overview

The main exporter matches its stated purpose, but the package also includes an undocumented obfuscated LLM helper that can forward selected prompt or file content, so it should be reviewed before installation.

Install only if you trust this publisher and are comfortable with the skill using your logged-in Chrome Xiaohongshu session and writing unencrypted exports to a local directory. Use a private, non-synced output folder for sensitive favorites. Do not invoke wc3-code.mjs unless you have inspected or removed it and explicitly trust the endpoint it will send prompt/file content to.

Vulnerability Patterns

• 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
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally

The original file is minified onto a single line; the formatting above only separates the relevant operations for readability.

Technical Analysis

The bundled wc3-code.mjs program accepts prompt text directly or reads it from a caller-selected file. It places that content in a JSON request and sends it through fetch() to LLM_ENDPOINT. While an operator may override the destination using WC3_LLM_ENDPOINT, the default endpoint is hidden behind an encoded string table and runtime decoder.

This behavior is materially different from the documented Skill workflow. SKILL.md states that the Skill uses deterministic Extension Relay operations and does not rely on an LLM pipeline. The documented entry point is skill.mjs, and the inspected call chain does not invoke wc3-code.mjs. Nevertheless, the unrelated executable is shipped in the project without documentation of its endpoint, data handling, or privacy implications.

Remediation

View remediation

Remediation Suggestions

1. Remove wc3-code.mjs if it is not required by the documented collection-export workflow.
2. If it is required, replace the obfuscated and minified implementation with readable source code.
3. Do not provide a concealed default endpoint. Require the user to configure the endpoint explicitly, or expose a clearly documented fixed destination.
4. Validate the endpoint scheme and host against an explicit allowlist. Require encrypted transport for non-loopback destinations.
5. Display the destination and categories of data being transmitted, then require explicit user approval before the first network request.
6. Restrict prompt-file access to files deliberately selected for submission and clearly warn that the complete file will be transmitted.
7. Document retention, privacy, authentication, and redirect behavior for the receiving service.
8. Keep unrelated LLM functionality in a separate package so it cannot be mistaken for part of the deterministic exporter.
9. Add tests ensuring that the documented skill.mjs entry point never imports, spawns, or otherwise invokes this helper.

• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• Trigger Abuse: Overly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
• MCP Least Privilege: Underdeclared Capability, Wildcard Permission, Missing Permission Declaration

Obfuscated Code

High

• Category: Supply Chain
• Confidence: 98% confidence

Finding

The presence of long encoded payload-like strings is a hallmark of packed or obfuscated code and prevents reviewers from easily determining embedded messages, endpoints, or logic. This is especially concerning when the skill already shows deceptive functionality inconsistent with its manifest.

Description-Behavior Mismatch

High

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

Finding

This file does not implement Xiaohongshu favorite export at all; it is an obfuscated generic LLM client that accepts arbitrary prompt/schema input and posts it to a configurable remote endpoint. That mismatch between declared purpose and actual behavior is a strong indicator of deceptive functionality and creates a hidden data-transfer channel inconsistent with a local backup skill.

Content

No source excerpt is available for this finding.

Context-Inappropriate Capability

High

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

Finding

The code reads prompt content from CLI or file, optionally reads schema/resume data, and sends all of it in a POST request to a remote LLM endpoint. In the context of a skill advertised as local backup/export from a logged-in browser session, this creates unjustified exfiltration risk for sensitive user content and workflow state.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

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

Finding

The README encourages bulk export of a user's favorites into local Markdown files but does not clearly warn that favorites may contain sensitive personal interests, private research topics, or copyrighted material that will be written to disk in a searchable, persistent form. In this skill's context, the omission matters because the entire purpose is large-scale local replication of account content, which increases the chance of accidental exposure via backups, shared folders, indexing, or later exfiltration by other software.

Content

No source excerpt is available for this finding.

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 90% confidence

Finding

The skill declares no explicit tool scope or permissions even though its documented behavior implies environment and network-capable code via a local relay service and filesystem writes. Missing scope boundaries increases the chance the agent invokes the skill without adequate review of what resources it can access, especially because it depends on a logged-in browser session and local services.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium

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

Finding

The activation text is broad enough to match generic export, backup, offline saving, or personal knowledge base requests, which could cause the skill to run in situations where the user did not specifically intend browser-session scraping of account-bound saved content. Because the skill exports private favorites from the currently logged-in account to local disk, over-triggering raises privacy and unintended data exposure risks.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 86% confidence

Finding

The script uses HTTP calls to a relay service and sends page-evaluation code plus extracted browser data as part of the export workflow. This is a network operation involving user/account context, but the file lacks a clear user-facing disclosure that browser data is being sent to a local relay component.

Content

No source excerpt is available for this finding.

Missing User Warnings

Medium

• Category: Not specified by scanner
• Confidence: 89% confidence

Finding

The script creates an output directory and later writes multiple Markdown and JSON files containing exported user favorites. Although the operation is core to the skill, this file itself provides no explicit user disclosure in a prompt, comment, or docstring warning that local files will be created from account data.

Content

No source excerpt is available for this finding.

Unbounded Resource Access

Medium

• Category: Excessive Agency
• Confidence: 75% confidence

Finding

Skill allows unbounded resource consumption (API calls, storage, compute). Without rate limits or quotas, a compromised or misbehaving agent can cause denial-of-service or cost overruns.

Missing User Warnings

Medium

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

Finding

The script sends prompt, schema, and resume data over the network without any user-facing disclosure in the file's behavior or manifest context. In a tool presented as a local export utility, silent network transmission materially increases privacy risk because users would not reasonably expect their data to leave the machine.

Content

No source excerpt is available for this finding.

Missing User Warnings

Low

• Category: Not specified by scanner
• Confidence: 84% confidence

Finding

Although the file mentions local Markdown export, it does not prominently warn users that the skill will create a persistent local corpus plus a summary.json manifest on disk, potentially containing private saved-content metadata and links. Insufficient disclosure can lead users to underestimate the persistence and sensitivity of the exported data.

Natural-Language Policy Violations

Low

• Category: Not specified by scanner
• Confidence: 82% confidence

Finding

Several string literals in the script's usage and error messages are in Chinese, with no indication that the user can select another language or locale. This can violate a language/locale policy when a specific language is imposed without opt-in or documented justification.
