LLM code scanners fail on streaming output, new approach proposed

By PulseAugur Editorial · [1 sources] ·

A developer building Cencurity, a security scanner for LLM-generated code, discovered a critical flaw in how security tools handle streaming output. Traditional scanners, designed for complete files, fail when applied to LLM responses delivered in small, arbitrary chunks via Server-Sent Events. This means patterns that would be caught in a full code block can be missed entirely if split across multiple chunks, leading to potential security vulnerabilities. The developer proposes a solution using a sliding window buffer that holds back a small portion of the text to ensure complete patterns can be analyzed in real-time without significantly delaying the developer's experience.
