Poisoning the Well: Defending Agentic Vector Databases from Diagnostic Key Leaks

A sophisticated AI assistant can be compromised by logging and saving diagnostic error messages containing sensitive credentials, such as API keys. This is known as Memory & Context Poisoning (OWASP ASI06). To protect against this, active response redaction should be enforced to prevent sensitive data from being written to the vector store. This is particularly important in AI agent contexts where memory is active and can be queried by malicious payloads. Engineers should take steps to prevent diagnostic error leaks from entering the vector database.
