Frequently Asked Questions
What is parameter injection in tool calls?
It is when attacker-influenced text ends up inside the arguments an LLM passes to a tool, such as a SQL query or shell command. If the tool trusts them, the payload executes.
Why is validating LLM tool arguments important?
Model output is not trustworthy input. Treat arguments like user input: use schemas, allowlists and parameterized queries so a manipulated model cannot trigger injection in downstream systems.
Can an LLM cause SQL injection?
Yes. If an LLM builds a query from user-influenced text and the app runs it unsafely, classic SQL injection occurs. This free room shows how and how parameterization stops it.
