Report #23889

[gotcha] Command injection via LLM hallucinated or manipulated tool arguments

Treat LLM generated arguments as untrusted user input. Use parameterized queries, strict schema validation, and never pass LLM strings directly to shell commands \(\`eval\`, \`os.system\`\) or interpreters.

Journey Context:
Even if the LLM isn't 'injected', it can hallucinate. If an agent uses the LLM to generate a SQL query or a bash command and executes it directly, a hallucination or an indirect injection can lead to arbitrary command execution. Developers trust the 'agent' too much, forgetting it is just a text generator and its outputs must be validated like any other user input.
