A.S.E 2.0: Understanding How Repository Context Impacts the Security of LLM-Generated Code

The paper introduces CASE-Bench, a benchmark of 145 repository-level tasks derived from real CVEs across 51 projects, each run in Docker with functional tests and proof‑of‑concept exploits. It evaluates 13 context‑construction methods and six controls across six LLMs, showing that functionality‑oriented context improves functional pass rates by up to 8.2 pp but only 3.7 pp for security, that omitting safeguards can drop secure pass rates by 8.1 pp, and that coding agents see relevant safeguards in only 27‑36 % of trajectories. These results highlight how repository context shapes the security of LLM‑generated code and guide the design of security‑aware context construction and evaluation.

Beyond Predefined Sinks: Security-Aware Dependency Analysis for LLM Agents

The paper introduces AgentSecGraph, a static analysis framework that builds a Security-Aware Agent Dependency Graph (Security-ADG) for each security-sensitive operation in large language model (LLM) agents. It enriches operation identity with agent relevance, source and dependency evidence, trust-boundary context, guard evidence, and external-effect semantics. The authors also present AgentSecBench, a corpus of 67 real-world LLM-agent repositories, and demonstrate that their analyzer identifies thousands of operation candidates, recovers substantial dependency and guard evidence, and distinguishes guarded behaviors from vulnerabilities with high accuracy.

Beyond Static Guarantees: Measuring the Static-Pass Dynamic-Fail Gap in Security-Sensitive and LLM-Generated Python Code

The paper introduces the Static‑Pass Dynamic‑Fail (SPDF) phenomenon, showing that static analysis can miss vulnerabilities that are exploitable at runtime. Using a three‑stage pipeline—static scanning, LLM‑driven CWE reasoning, and autonomous exploit verification—it evaluated 1,355 Python samples and found that 14.53% of samples that passed static checks were actually exploitable. The study highlights that static‑analysis success and runtime security are distinct assurance layers, especially for AI‑generated and security‑sensitive code.
