InjecMEM: Memory Injection Attack on LLM Agent Memory Systems
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- Researchers demonstrated InjecMEM, an attack that poisons LLM agent memory systems with a single malicious input to steer future responses toward attacker-specified outputs.
- Why it matters
- Engineers building or deploying LLM agents with persistent memory systems need to understand this vulnerability before production deployment.
- Watch out
- The attack requires only one interaction without memory access, but real-world effectiveness depends on memory retrieval mechanisms and may vary across different system architectures.
