If user-controlled data is included in a system prompt or the description of tools for an agentic system, an attacker can manipulate the instructions +that govern the AI model's behavior, bypassing intended restrictions and potentially causing sensitive +data leaks or unintended operations. +

+ + + +

Do not include user input in system-level or developer-level prompts or tool descriptions. Use methods meant for user input or messages with a "user" role to provide user content or context to the AI model. + +If user input must influence the system prompt or tool description, validate it against a fixed allowlist of permitted values.

+ + + +

In the following example, a user-controlled value is inserted directly into a system-level prompt +without validation, allowing an attacker to manipulate the AI's behavior.

+ +

One way to fix this is to provide the user-controlled value in a message with the "user" role, +rather than including it in the system prompt. The model then treats it as user content instead of +as a trusted instruction.

+ +

Alternatively, if the user input must influence the system prompt, validate it against a fixed +allowlist of permitted values before including it in the prompt.

+ + + + +

Prompt injection is not limited to system prompts. In the following example, which uses an agentic +framework, a user-controlled value is included in the description of a tool that is exposed to the +model. An attacker can use this to manipulate the model's behavior in the same way.

+ +

The fix keeps the tool description as a fixed, trusted string and passes the user-controlled topic +as part of the user input instead, so the model treats it as user content rather than as a trusted +instruction.

    If untrusted input is included in a user-role prompt sent to an AI model, an attacker can inject +instructions that manipulate the model's behavior. This is known as indirect prompt injection +when the malicious content arrives through data the model processes, or direct prompt injection +when the attacker controls the prompt directly.

    + +

    Unlike system prompt injection, user prompt injection targets the user-role messages. Although +user messages are expected to carry user input, passing unsanitized data directly into structured +prompt templates can still allow an attacker to override intended instructions, extract sensitive +context, or trigger unintended tool calls.

    +     + + +

    To mitigate user prompt injection:

    +
      +
    • Ensure that all data flowing into user-input is intended and necessary for the purpose of the AI system.
      • +
    • Ensure the system prompt clearly describes the purpose, scope and boundaries of the AI system. Instruct the system to deny input that falls outside these boundaries.
      • +
    • If creating a prompt out of multiple user-controlled values, assume that each of them can be malicious. Ensure the range of possible values is restricted and validated. +For example, if a prompt includes a question and the intended language to respond in, validate that the language is one of the supported options.
      • +
    • Consider using guardrails on the input like the OpenAI guardrails library to enforce constraints and prevent malicious content from being processed.
      • +
    • Apply output filtering to detect and block responses that indicate prompt injection attempts.
      • +
    +     + + +

    In the following example, user-controlled data is inserted directly into a user-role prompt +without any validation, allowing an attacker to inject arbitrary instructions.

    + + +

    The following example applies multiple mitigations together, and only includes data that is +necessary for the task in the prompt:

    +
      +
    • The user-controlled value that selects behavior (the response language) is validated against a +fixed allowlist before it is used in the prompt, restricting its possible values.
      • +
    • The request is sent through a guarded client, so an input guardrail (here, the OpenAI guardrails +library) inspects the user input and blocks prompt-injection attempts before the model sees it.
      • +
    • The system prompt clearly describes the assistant's scope and instructs it to ignore embedded +instructions and refuse anything outside that scope.
      • +
    • Output filtering uses a separate LLM call to inspect the model's response and blocks it if it +has leaked the system prompt or other internal instructions, complementing the input guardrail.
