Agent Memory and Context Poisoning

Description

Adversarial inputs commit malicious content into agent memory, vector stores, or context window — evicting safety instructions or persisting across sessions.

Example

An attacker plants instructions in a shared memory store; subsequent agent sessions inherit the poisoned context and act on the attacker's directives across multiple users.

Assets Affected

Agent Memory / Cache

Dataset / RAG

AI Agent

Mitigation
  • Validate inputs before commitment to memory
  • partition memory per agent and per tenant
  • integrity-check stored vectors
  • limit context size
  • monitor for cross-session anomalies.
Standards Mapping
