Decompose LLM vulnerability discovery into sub-tasks
Break down LLM vulnerability discovery into distinct, measurable steps for better evaluation.
Vulnerability discovery is a composite ability that can be decomposed into distinct sub-tasks for more precise measurement.
Instead of a single end-to-end verdict, evaluating an LLM's ability to comprehend source code, infer input constraints, construct inputs, execute them, and iteratively correct from feedback allows for localization of failure points and more targeted improvements.
The SWE-Test benchmark decomposes discovery into Open-loop (input construction without feedback), Feedback-enabled (input construction with a distance oracle), and Online Arena (path exploration by coverage gain) modes.
Evaluate LLM vulnerability discovery by breaking it into constituent parts: code comprehension, input constraint inference, input construction, execution, and feedback-driven correction. This allows for more granular assessment and targeted improvement of LLM security agents.
This decomposition helps isolate specific weaknesses in an LLM's reasoning or generation process, moving beyond a simple pass/fail to understand where the model struggles.
