Security checks for vulnerabilities and agentic risk

Overview

The skill supports read-only Douyin creator research with clearly disclosed credential setup and third-party software use.

Trust the SocialDataX service and CLI before supplying an API key, and prefer a reviewed, fixed package version. Keep credentials in supported secret storage and out of chat and version control. Set page or item limits to control usage costs. This review covered the complete bundled skill instructions; it could not verify the external CLI implementation or publisher identity.

Vulnerability Patterns

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Findings (5)

MCP server referenced without pinned version: 'npx -y socialdatax-skills'.

Medium

Category: MCP Rug Pull
Confidence: 99% confidence
Finding: The user-posts command executes socialdatax-skills@latest through npx -y, automatically accepting a mutable package version rather than a reviewed release. A compromised or malicious future release could execute with the agent's permissions and access its API key and other accessible local data; the documented read-only API purpose does not restrict package execution.
Content: No source excerpt is available for this finding.

MCP server referenced without pinned version: 'npx -y socialdatax-skills'.

Medium

Category: MCP Rug Pull
Confidence: 99% confidence
Finding: The profile-URL user-posts example also runs socialdatax-skills@latest with automatic npx confirmation, so the executed code can change without changes to the skill. Although this is a direct CLI rather than an MCP server, the supply-chain exposure is real: a compromised release could access the injected API key and act with the command process's permissions.

MCP server referenced without pinned version: 'npx -y socialdatax-skills'.

Medium

Category: MCP Rug Pull
Confidence: 99% confidence
Finding: The user-series command resolves the mutable @latest tag and runs the resulting package without an interactive installation check. A malicious package update could execute arbitrary code in the agent environment, including reading the API key; requesting read-only series data does not constrain that code.
Content: No source excerpt is available for this finding.

MCP server referenced without pinned version: 'npx -y socialdatax-skills'.

Medium

Category: MCP Rug Pull
Confidence: 99% confidence
Finding: The profile-URL user-series example repeats the same unpinned execution path through npx -y socialdatax-skills@latest. This creates a supply-chain risk if the package or publishing account is compromised, with potential credential theft or unauthorized actions under the agent's permissions; there is no evidence here that such a compromise has occurred.
Content: No source excerpt is available for this finding.

MCP server referenced without pinned version: 'npx availability'.

Medium

Category: MCP Rug Pull
Confidence: 70% confidence
Finding: npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.
Content: No source excerpt is available for this finding.
