Unvalidated Trust: Cross-Stage Vulnerabilities in Large Language Model Architectures

Abstract

As Large Language Models are increasingly integrated into complex automated pipelines, security vulnerabilities that extend beyond simple input filtering become a practical concern. This work presents a mechanism-centered taxonomy of 41 recurring risk patterns, identified through a standardized, text-only evaluation protocol on commercial LLMs under default settings. Our empirical observations reveal systemic weaknesses in unvalidated trust inheritance across processing stages, which allows infe
