AltxtAI — agentic threat model
AltxtAI is a low-risk, single-purpose utility focused on generating alt text from images. Its primary security risks stem from processing untrusted image inputs (adversarial or exploit payloads) and the potential for generating inappropriate or injection-prone text outputs.

Scored with the canonical OWASP AIVSS formula (AIVSS calculator reference); agentic risk factors estimated from the agent’s described capabilities.
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.
Utilizes vision-language models to interpret images. Vulnerable to adversarial image perturbations that manipulate the generated alt text, potentially causing brand damage or SEO spam injection.
Processes user-uploaded images or image URLs. Risks include processing malicious image files designed to exploit parser vulnerabilities, or data privacy concerns regarding sensitive information contained within uploaded images.
Not certain from the listing — likely uses a simple pipeline rather than an agentic framework. If orchestration exists, risks are limited to insecure handling of API keys and lack of input sanitization before passing to the model.
Not certain from the listing — presumably hosted as a SaaS platform. Standard web application risks apply, including potential Server-Side Request Forgery (SSRF) if the service fetches images from user-provided URLs.
Not certain from the listing — unknown if there are guardrails to detect and block offensive, biased, or malicious text generation from being output to the user.
Not certain from the listing — while it aids in web accessibility compliance (WCAG), its own data handling policies, encryption standards, and user authentication mechanisms are not detailed.
Not certain from the listing — likely operates as a standalone tool or CMS plugin (e.g., WordPress, Shopify). If integrated, a compromise could allow automated injection of malicious scripts (XSS) into the host website's image metadata.
