Security audit

Jewish Parsha Summary

Security checks for vulnerabilities and agentic risk

Overview

This skill does what it says: it fetches weekly Torah portion text from disclosed public APIs and summarizes it without persistence or hidden local access.

Before installing, users should be comfortable with the skill making outbound requests to Hebcal and Sefaria for calendar and Torah text data. It does not appear to need local files, credentials, or persistent access.

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

Finding

The skill explicitly depends on external network access to Hebcal and Sefaria, but it does not declare any tool scope or allowed network capabilities. That creates an authorization and review gap: an agent may invoke networked behavior without clear least-privilege boundaries, making data exfiltration or unintended outbound requests harder to govern.

Finding

The 'Use when' text says to use the skill when a user wants a 'quick parsha overview, weekly summary, or needs parsha content for a dvar Torah outline.' These are broad natural-language conditions rather than narrowly scoped trigger phrases, which could cause the skill to match general religious-study requests without clear boundaries or exclusions.
