CVE-2026-100840— MONAI through 1.6.0 Remote Code Execution via bundle configuration

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 1.6.0 及之前版本在 bundle 配置引擎中存在远程代码执行漏洞。该漏洞允许 _target_ 值被解析为任意可导入的可调用对象，而未设置允许列表（allow list）；同时，$ 表达式会被直接传递给 Python 的 eval() 函数执行。攻击者可以发布包含精心构造配置的恶意 bundle，当受害者使用 monai.bundle.load() 或 monai.bundle.run() 加载该 bundle 时，其中的任意代码将被执行。

Vulnerability Title
MONAI through 1.6.0 Remote Code Execution via bundle configuration
Source: CVE Program / CVE List V5
Vulnerability Description
MONAI through 1.6.0 contains a remote code execution vulnerability in the bundle configuration engine that resolves _target_ values to arbitrary importable callables without an allow list and passes $ expressions to Python eval(). Attackers can publish a malicious bundle with crafted configuration containing arbitrary code that executes when a victim loads the bundle using monai.bundle.load() or monai.bundle.run().
