Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

ESPectre 是一个面向 ESP32 的 Wi‑Fi 运动感知平台。在 3.0.0-rc1 版本之前，Micro-ESPectre 的分析工具（包括 tools/6_optimize_filter_params.py、tools/1_analyze_raw_data.py 和 tools/10_train_ml_model.py）通过 micro-espectre/tools/csi_utils.py 启用 NumPy 的 pickle 支持，并使用直接加载器来读取 NPZ 数据集。恶意的数据集贡献者或拉取请求

Vulnerability Title
ESPectre: Unsafe Deserialization on .npz dataset leads to Code Execution
Source: CVE Program / CVE List V5
Vulnerability Description
ESPectre is a Wi-Fi motion sensing platform for ESP32. Prior to 3.0.0-rc1, Micro-ESPectre analysis tools, including tools/6_optimize_filter_params.py, tools/1_analyze_raw_data.py, and tools/10_train_ml_model.py, load NPZ datasets with NumPy pickle support enabled through micro-espectre/tools/csi_utils.py and a direct loader. A malicious dataset contributor or pull-request author can place an object-typed array in a .npz file under micro-espectre/data, causing pickle-controlled code to execute as the maintainer or developer when a documented analysis tool accesses the field. This issue is fixed in version 3.0.0-rc1.
