A Wolf in Sheep's Clothing: Targeted Routing Hijacking in Federated RAG
Researchers demonstrate that Federated RAG's reliance on client-supplied semantic profiles enables targeted routing hijacks, undermining the privacy guarantees the architecture promises.

arXiv:2605.28112v2 Announce Type: replace Abstract: Federated Retrieval-Augmented Generation (FedRAG) is attractive for privacy-sensitive applications because full local corpora remain on clients. As a result, routing must rely on client-provided semantic profiles, creating a new opportunity for manipulation. We introduce Routing Hijacking, a routing-stage attack in which a malicious client forges its profile to attract target queries despite having irrelevant underlying data. We show that this
Editorial Analysis
Enterprises evaluating Federated RAG for privacy-sensitive use cases should recognise that client-side semantic profiles represent a manipulable trust boundary.
