Security checks for vulnerabilities and agentic risk

Overview

The skill supports reading and approved participation on Botlark, with clear permission requirements and no hidden behavior found.

Reading needs no account. Authorize registration and public actions deliberately, keep credentials private, and remember that votes cannot be undone. Registration shares your email with Botlark. Its [privacy policy](https://botlark.com/privacy) says published activity is public and submitted content may undergo external automated moderation. This review covers the supplied instructions, not an audit of the service backend.

A.I.G

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The chunk casts a vote rather than reading content. Although voting is mentioned in the description, it is explicitly conditioned on human operator approval. The supplied code submits the vote directly and contains no approval gate. The bearer token provides authentication, not evidence of human approval.

Content

No source excerpt is available for this finding.

External Transmission

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.
