Alibaba Cloud AI Translation Anytrans

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Alibaba Cloud TongyiTranslate workflow helper with expected credential use and metadata fetching, with no evidence of hidden execution, exfiltration, persistence, or destructive behavior.

Install only if you intend to let the agent help with Alibaba Cloud TongyiTranslate workflows. Use least-privilege Alibaba Cloud credentials, review any create/update/modify/set operation before execution, and keep generated evidence under the declared output directory.

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 (8)

Tainted flow: 'timeout' from os.getenv (line 34, credential/environment) → urllib.request.urlopen (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.

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The skill claims it manages TongyiTranslate resources and operational workflows, but the described behavior centers on OpenAPI metadata discovery rather than actual AnyTrans service operations. This mismatch is dangerous because users or orchestration systems may trust the skill for cloud resource management while it performs different network actions, undermining auditability and enabling unexpected data access or misleading execution paths.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
93% confidence
Finding

The skill advertises executable workflows that rely on environment variables, filesystem writes, and network access, but it does not declare any explicit tool scope or permission boundaries. In an agent environment, this can cause over-privileged execution or make the agent invoke the skill in contexts where sensitive credentials and outbound access are available without clear user visibility.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The invocation description is broad enough to match many generic cloud-management or troubleshooting requests, increasing the chance that an agent selects this skill outside its narrow intended use. In this context, that is more dangerous because the skill also involves credentials, network calls, and file output, so accidental invocation could expose cloud metadata, misuse privileges, or create confusing side effects.
