CVE-2026-109361— MONAI 1.2.0 before 1.6.1 Insecure Deserialization RCE via nnUNetV2Runner postprocessing_file Path

Quick assessment

Affected
Project-MONAI MONAI
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.

MONAI 1.6.1 之前的 1.2.0 版本在 nnUNetV2Runner 中存在不安全的反序列化漏洞。该漏洞会对从 inference_information.json 文件中读取的 postprocessing_file 路径进行 unpickle 操作，而未将其限制在结果目录内。攻击者若能够修改 inference_information.json 文件，即可将该路径指向文件系统中其他位置的恶意 pickle 文件，从而在 predict_ensemble_postprocessing 执行时触发代码执

MONAI 1.2.0 before 1.6.1 Insecure Deserialization RCE via nnUNetV2Runner postprocessing_file Path
Source: CVE Program / CVE List V5
Vulnerability Description
MONAI 1.2.0 before 1.6.1 contains an insecure deserialization vulnerability in nnUNetV2Runner that unpickles the postprocessing_file path read from inference_information.json without confining it to the results directory. Attackers who can modify inference_information.json can point it at a malicious pickle elsewhere on the filesystem to execute code when predict_ensemble_postprocessing runs.
