contents Large Language Models (LLMs) have become powerful tools for automated code generation. However, these models often overlook critical security practices, which can result in the generation of insecure code that contains vulnerabilities-weaknesses or flaws in the code that attackers can exploit to compromise a system. However, there has been limited exploration of strategies to guide LLMs in generating secure code and a lack of in-depth analysis of the effectiveness of LLMs in repairing code containing vulnerabilities. In this paper, we present a comprehensive evaluation of state-of-the-art LLMs by examining their inherent tendencies to produce insecure code, their capability to generate secure code when guided by self-generated vulnerability hints, and their effectiveness in repairing vulnerabilities when provided with different levels of feedback. Our study covers both proprietary and open-weight models across various scales and leverages established benchmarks to assess a wide range of vulnerability types. Through quantitative and qualitative analyses, we reveal that although LLMs are prone to generating insecure code, advanced models can benefit from vulnerability hints and fine-grained feedback to avoid or fix vulnerabilities. We also provide actionable suggestions to developers to reduce vulnerabilities when using LLMs for code generation.
