LLM coding assistants vulnerable to minor prompt changes

By PulseAugur Editorial · [2 sources] ·

A new research paper from arXiv demonstrates that minor changes to prompts given to LLM coding assistants can introduce significant security vulnerabilities into the generated code. The study applied token-level mutations to prompts across multiple models and programming languages, finding that even single-character changes could shift code from secure to vulnerable. Analysis of the models' internal states indicated that these vulnerabilities are partially encoded in prompt representations, with input-handling flaws being more predictable than secure-defaults flaws. AI

IMPACT Minor prompt variations can introduce security risks in LLM-generated code, necessitating new security checks during development.
