Introduction to Memory Poisoning
The OpenAI Agents SDK is rapidly becoming the standard for building production AI agents, but as agents grow more capable and stateful, a critical attack surface emerges: memory poisoning, also known as OWASP ASI06. This type of attack occurs when an attacker injects malicious data via any user-controlled input that gets stored in the agent's memory. If this poisoned content enters an agent's context, it can override system instructions across sessions, causing unintended behavior.
The OpenAI Agents SDK uses a typed context object passed to every agent run, which provides a natural validation hook via field validator from Pydantic. By using a Pydantic BaseModel for the context, developers can block ASI06 memory poisoning attempts before they enter the context. This is achieved through the use of a MemoryGuard class, which scans the input data for any malicious content and raises a ValueError if any is found.
Understanding ASI06 Memory Poisoning
ASI06 Memory Context Poisoning is listed as one of the top risks for production agents in the OWASP Top 10 for Agentic AI Systems. The attack is simple: an attacker injects malicious data via any user-controlled input that gets stored in the agent's memory. If this poisoned content enters an agent's context, it can override system instructions across sessions, causing unintended behavior. The OpenAI Agents SDK provides a secure way to defend against this type of attack using the Pydantic context architecture.
The integration pattern was validated in a public thread with an OpenAI SDK maintainer, ensuring that the solution is idiomatic and effective. By using the MemoryGuard class, developers can block ASI06 memory poisoning attempts before they enter the context, providing a secure and reliable way to build production AI agents. The MemoryGuard class fires on every context update, whether the content comes from user input, tool output, or a retrieved vector store chunk.
Defending Against Memory Poisoning
To defend against memory poisoning, developers can use the MemoryGuard class to scan the input data for any malicious content. The MemoryGuard class raises a ValueError if any malicious content is found, preventing it from entering the agent's context. This provides a secure and reliable way to build production AI agents that are resistant to memory poisoning attacks.
The OpenAI Agents SDK provides a secure way to defend against memory poisoning using the Pydantic context architecture. By using a Pydantic BaseModel for the context, developers can block ASI06 memory poisoning attempts before they enter the context. The MemoryGuard class fires on every context update, providing a secure and reliable way to build production AI agents. The MemoryGuard class is easy to use and provides a simple and effective way to defend against memory poisoning.
