- Lane: Research
- Severity: 1 (Research / proof of concept): Proof‑of‑concept attack, no confirmed exploitation
- Fix status: Fix status unknown
- First reported: 2026-11-05
- AI role: AI-enabled attack
- Products: open-weight LLM agents

## Summary

Researchers show that local open-weight LLM agents can be used to automatically generate inputs that trigger crashes in vulnerable software builds. The proof‑of‑concept demonstrates an AI‑enabled attack without evidence of real‑world exploitation.
