Quick assessment

Affected
Khronos Group nnef
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.

Khronos NNEF-Tools 中，nnef 版本最高至 1.0.10 以及 nnef-tools 版本最高至 1.0.11 存在路径遍历漏洞。攻击者可通过构造的变量标签，在用户执行转换、保存或生成权重操作时，利用 graph.nnef 文件中包含的 “../” 序列或绝对路径，在模型目录之外创建或覆盖 .dat 文件，从而将文件写入到预期范围之外。
