Newer and Bigger, but Safer? A Longitudinal Study of the Functionality-Security Gap in LLM-Generated Code

Large Language Models LLMs are widely used to generate code. Although their functional plausibility keeps improving, the generated code often contains security vulnerabilities. The functionality-security gap captures code that passes functional tests but fails security tests. A recent longitudina...

LLMVul: A Vulnerability-Labeled Dataset of LLM-Generated C/C++ Functions from Real Production Repositories

Large language models LLMs are increasingly used to generate and assist with software development, yet existing vulnerability datasets largely focus on human-written code or controlled prompting environments. This limits the ability to study security weaknesses in LLM-generated code as it appears...

Prompt Structure Redistributes, Not Reduces: An Empirical Analysis of Security-Weaknesses in LLM-Generated Python Code

Large Language Models LLMs increasingly generate code from natural-language prompts, making prompt engineering a key mechanism for shaping the security of generated software. Structured and security-oriented prompts are widely used to encourage safer code, yet their effects extend beyond whether...

IBM Langflow OSS Code Execution Vulnerability (CNVD-2026-32369)

IBM Langflow OSS is the open-source version of Langflow that IBM officially integrates and promotes. IBM Langflow OSS has a code execution vulnerability. This vulnerability stems from the failure to properly handle components generated by the LLM during the Agentic Assistant validation process. T...

Arbitrary Code Injection

Overview flowise is a Flowiseai Server Affected versions of this package are vulnerable to Arbitrary Code Injection via the run method in the CSVAgents class. An attacker can execute arbitrary code in the context of the server process by sending crafted prompts to a chatflow using the CSV Agent...

PYSEC-2026-562 vanna vulnerable to remote code execution caused by prompt injection

In the latest version of vanna-ai/vanna, the vanna.ask function is vulnerable to remote code execution due to prompt injection. The root cause is the lack of a sandbox when executing LLM-generated code, allowing an attacker to manipulate the code executed by the exec function in...
