Transient Turn Injection Exposes Stateless Multi-Turn Vulnerabilities in LLMs

arXiv·high signal

Researchers introduce Transient Turn Injection (TTI), a multi-turn attack technique that exploits stateless moderation by distributing adversarial intent across isolated interactions. TTI uses automated attacker agents to iteratively probe and evade safety guardrails in both commercial and open-source LLMs. The attack surface is particularly concerning because most production deployments use stateless turn-by-turn moderation that cannot detect distributed intent across sessions.
