Reinforcement Learning from Human Feedback (RLHF) is central to aligning Large Language Models (LLMs), yet it introduces a critical vulnerability: an imperfect Reward Model (RM) can become a single point of failure when it fails to penalize unsafe behaviors. While existing red-teaming approaches...

Recent work has shown that fine-tuning on insecure code data can trigger an emergent misalignment (EMA) phenomenon, where models generate malicious responses even to prompts unrelated to the original insecure code-writing task. Such cross-domain generalization of harmful behavior underscores the...

Large Language Models (LLMs) are evolving rapidly on code generation tasks. While it is important to evaluate their code generation accuracy, ensuring they follow responsible practices is equally critical. Some of the previous works use tools such as CodeQL to match patterns against Common Weakne...
