kekebe — agentic threat model

6.7AIVSS 6.7 · Medium

The agentic risk of kekebe is extremely low due to its single-purpose, non-agentic nature as an image style-transfer utility. Primary security concerns are classic web application vulnerabilities, such as malicious file uploads and server-side processing exploits, rather than agentic autonomy risks.

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✓ mapped

Uses image-to-image generative models (likely diffusion or GAN-based) to apply Ghibli styling. Threats include adversarial image inputs designed to bypass safety filters or exploit the underlying model's parser.

L2 · Data Operations⚠ not certain from listing

Not certain from the listing — The data pipeline likely involves transient processing of user-uploaded images. Threats include unauthorized retention or exposure of user images, and potential poisoning of the style-transfer training set if open-source weights are updated without validation.

L3 · Agent Frameworks⚠ not certain from listing

Not certain from the listing — The tool does not appear to use an agentic orchestration framework, operating instead as a direct input-output pipeline. If orchestration exists, threats are limited to insecure handling of file parameters.

L4 · Deployment & Infrastructure⚠ not certain from listing

Not certain from the listing — Hosted web application infrastructure. The primary threat is remote code execution (RCE) or denial of service (DoS) via malicious image payloads that exploit vulnerabilities in image processing libraries (e.g., Pillow, LibTIFF).

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — No observability or logging mechanisms are mentioned. Gaps include a lack of input validation to filter out malicious files or inappropriate content before processing.

L6 · Security & Compliance (cross-cutting)✓ mapped

The 'no signup required' model means there are no identity or access management controls. While this protects user privacy, it exposes the service to automated abuse, API scraping, and resource exhaustion.

L7 · Agent Ecosystem✓ mapped

This is a standalone vertical tool with no multi-agent interactions or ecosystem integrations described, making ecosystem-level threats negligible.
