All knowledge articles on risks in LLM applications and AI pipelines. Each entry explains the topic briefly and links to the in-depth article.
LLM applications
Risks in applications built on language models 10 topics-
Prompt injection
Inputs – typed directly or hidden in documents, web pages and emails – make a model ignore its instructions or follow someone else’s.
Article coming soon -
Sensitive information disclosure
A model reveals confidential data – from its training data, the conversation context or connected systems.
Article coming soon -
Excessive agency
An agent can do more than its task requires: too many tools, too broad permissions, too little human confirmation.
Article coming soon -
Supply chain
Risks that enter an application through third-party models, datasets, plugins and libraries.
Article coming soon -
Data and model poisoning
Manipulated training, fine-tuning or embedding data deliberately change how a model behaves.
Article coming soon -
Unbounded consumption
Unthrottled requests drive up cost and load, or allow a model to be systematically extracted.
Article coming soon -
Misinformation
Convincingly worded but wrong output that people or downstream systems rely on.
Article coming soon -
Vector and embedding weaknesses
Weaknesses in RAG systems: missing access separation, manipulated or extracted vector data.
Article coming soon -
Improper output handling
Model output is processed without validation – as HTML, SQL or a shell command – and reopens classic vulnerabilities.

AI pipelines
From the data to the inference endpoint 5 topics-
Data & RAG ingestion
Whoever can feed training, fine-tuning or retrieval data can influence how the system behaves.
Article coming soon -
Model supply chain
Provenance and integrity of models, weights and dependencies – including registries and unsafe file formats.
Article coming soon -
Agents & tool access
MCP servers, tool permissions and automation decide what a manipulated agent can actually do.
Article coming soon -
Inference infrastructure
Model servers and APIs are services like any other: exposed, often weakly isolated, rarely rate-limited.
Article coming soon -
Secrets & keys
Model provider API keys and credentials easily end up in prompts, logs and pipeline variables.
