Security checks for vulnerabilities and agentic risk

Overview

This is a static reference skill that mixes number-5 cultural content with disclosed personal/project profile information, with no code execution or hidden persistence.

Install this only if you want a mixed reference/profile skill: it may surface Chen Lang's email, profile, project links, and OpenClaw-related promotional content alongside number-5 cultural explanations. No executable or privileged behavior was found.

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)

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The manifest describes a cultural reference skill about the number 5, but the body embeds unrelated personal biography, contact details, and product promotion. This creates deceptive scope expansion: a user or downstream agent may invoke the skill for innocuous cultural questions and receive unsolicited personal/project content that was not justified by the declared purpose.

Content

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The activation scope is broadened beyond number-culture queries to include profile and project-matrix questions, despite the skill being presented as a cultural meaning skill. Ambiguous triggering can cause the wrong skill to activate and inject unrelated promotional or personal content into conversations where users did not request it.

Context-Inappropriate Capability

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The skill exposes personally identifying and contact information that is not necessary for answering questions about the cultural meaning of number 5. In an agent setting, unnecessary PII can be redistributed, surfaced unexpectedly to users, or harvested through benign-seeming prompts, increasing privacy and social-engineering risk.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

Including direct contact information in the skill without a user-facing privacy warning or purpose limitation can lead to unintended disclosure and reuse. In conversational systems, this kind of embedded contact data may be surfaced repeatedly, copied into logs, or exploited for spam, targeting, or impersonation.

Content

No source excerpt is available for this finding.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
78% confidence
Finding

The description specifies the skill as a Chinese-English version, which implies a fixed bilingual presentation rather than letting the user choose a preferred language. Under the language/locale policy, forcing a specific language without opt-in can be a policy concern unless clearly justified.
