hunt-ssrf (Claude-BugHunter) — agentic threat model

8.7AIVSS 8.7 · High

This agent is an offensive security skill designed to generate and execute complex SSRF payloads, presenting high risk if misused or hijacked due to its capability to target cloud metadata and internal services, though it mandates out-of-band confirmation to prevent false positives.

OWASP AIVSS score rationale

AIVSS = (CVSS_Base + AARS) × Mitigation_Factor, where AARS = (10 − CVSS_Base) × (Factor_Sum / 10) × ThM

MAESTRO 7-layer threat model

Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.

L1 · Foundation Models⚠ not certain from listing

Not certain from the listing — relies on underlying LLMs (likely Claude given the name) which are susceptible to jailbreaks or prompt injection that could bypass safety filters to target unauthorized, non-consenting networks.

L2 · Data Operations✓ mapped

Utilizes a specialized dataset of 15 disclosed SSRF reports and patterns. If this local knowledge base is poisoned or manipulated, the agent could be tricked into generating benign payloads or sending exfiltration data to malicious third-party OOB servers.

L3 · Agent Frameworks✓ mapped

Orchestrates multi-step SSRF chains (e.g., DNS rebinding, gopher-to-Redis). Vulnerable to tool misuse or insecure tool integration if the framework executing these payloads does not strictly validate target inputs, potentially allowing local file inclusion or command injection on the runner.

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — the hosting environment requires strict outbound network controls. If the agent runner is not sandboxed, executing SSRF payloads locally could result in loopback exploitation or local cloud metadata compromise of the runner's own host.

L5 · Evaluation & Observability✓ mapped

Features a mandatory out-of-band (OOB) Collaborator confirmation mechanism for blind SSRF to verify findings, which acts as a built-in validation guardrail to prevent false positives and track payload execution.

L6 · Security & Compliance (cross-cutting)⚠ not certain from listing

Not certain from the listing — lacks explicit authorization, scoping, or consent verification mechanisms in the description to ensure the offensive payloads are only launched against legally approved targets.

L7 · Agent Ecosystem✓ mapped

Designed as an offensive 'skill' or sub-agent. If integrated into a larger multi-agent pentesting framework, a compromise or malicious instruction from a coordinator agent could weaponize this skill against unauthorized infrastructure.
