Exposure and failure modes

Risk Catalogue

Observed exposure paths where generative AI connects language to data, identity, tools, permissions, or decisions before governance has enough grip.

Data and Model Poisoning

Training data, fine-tuning datasets, or embeddings are deliberately manipulated to introduce vulnerabilities, backdoors, or biases that compromise model security and behaviour.

Improper Output Handling

Model-generated output is passed to downstream systems without validation or sanitisation, enabling injection attacks through AI-generated content.

Misinformation

The model generates false or misleading information presented with apparent authority, which users may accept without verification, with legal, reputational, or security consequences.

System Prompt Leakage

Internal system instructions, business rules, or configuration not intended for end users are exposed through model responses, revealing logic and enabling targeted follow-on attacks.

Unbounded Consumption

The application permits uncontrolled resource usage or model queries — without rate, cost, or volume limits — enabling denial of service, financial exhaustion, or service abuse.

Vector and Embedding Weaknesses

Systems that generate, store, or query vector embeddings in RAG architectures introduce their own security risks: injection through indexed data, cross-tenant information leakage, and retrieval manipulation.

MCP Channel Trust

The trust channel between an MCP client and server can carry malicious content, intercepted requests, or manipulated trust dialog, allowing an attacker to control agent behavior through the communication channel.

Agentic Supply Chain Compromise

An attacker-controlled artifact reaches an AI coding agent through plugin resolution, symlink paths, model cache, or CI trigger, and executes with the agent's privileges.
