- Lane: Research
- Severity: 1 (Research / proof of concept): Proof‑of‑concept prompt extraction, no confirmed real‑world exploitation
- Fix status: Fix status unknown
- First reported: 2026-11-03
- AI role: Attack on AI

## Summary

A study shows adversaries can reconstruct prompts from a single public synthetic video, enabling unauthorized reuse and editing of generated content. The attack adapts captioning and optimization techniques but achieves limited fidelity, exposing a new vector for prompt leakage.

## What to do

Implement watermarking and access controls to protect prompt confidentiality in video generators.
