Singapore Pools TOTO Results

Security checks for vulnerabilities and agentic risk

Overview

This skill does what it says: it runs a bundled Python script to fetch public Singapore Pools TOTO result data from official URLs and summarize it.

Install only if you are comfortable with the agent running the bundled Python script and making outbound requests to singaporepools.com.sg for public lottery result data. For stronger governance, prefer environments that enforce domain-scoped network permissions.

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

Finding

The skill instructs the agent to run a network-fetching script, but the manifest does not declare any explicit tool scope such as allowed tools or permissions. This creates a least-privilege and governance gap: an agent may be permitted to perform network access implicitly without the skill clearly constraining or documenting that capability, making misuse, policy bypass, or accidental expansion of runtime privileges more likely.
