LangChain ChromaDB RAG vulnerability allows metadata poisoning

A vulnerability has been discovered in LangChain's integration with ChromaDB that allows attackers to poison Retrieval-Augmented Generation (RAG) systems. By injecting high-priority metadata into documents, malicious content can be made to rank above legitimate information, regardless of semantic relevance. This exploit, affecting specific versions of LangChain and ChromaDB, could impact systems in sectors like insurance, legal, and medical, with the only immediate defense being output filtering at the API layer.
