Security audit

agent-bom vulnerability intel

Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly scoped vulnerability lookup helper that discloses its external advisory queries and avoids credential collection, persistence, and automatic remediation.

Install only if you are comfortable with package names, versions, ecosystems, PURLs, and advisory IDs being sent to public vulnerability databases during online checks. For private or sensitive dependency names, use the skill's offline-review mode or approve lookups case by case.

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

Direct Prompt Extraction

High
Category
System Prompt Leakage
Confidence
85% confidence
Finding

Skill contains instructions that could directly expose system prompts, internal rules, or hidden instructions to users or external parties.

available vulnerability database. Do not call a clean offline result equivalent
to a fresh OSV/GHSA/NVD lookup.

## Output Rules

- Show CVE/GHSA/PYSEC aliases together when available.
- Include severity source, fix version, EPSS, KEV status, CWE, and advisory

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

External Transmission

Data Exfiltration
Confidence

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
