CVE-2026-28400— Docker Model Runner Unauthenticated Runtime Flag Injection via _configure Endpoint

Quick assessment

Affected
docker model-runner
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.

Docker Model Runner是Docker开源的一个Docker模型运行器。 Docker Model Runner 1.0.16之前版本存在安全漏洞，该漏洞源于未经验证的POST端点接受任意运行时标志，可能导致攻击者写入或覆盖任意文件，进而破坏容器、镜像、卷和构建历史，或在特定配置下实现容器逃逸。

Vulnerability Title
Docker Model Runner Unauthenticated Runtime Flag Injection via _configure Endpoint
Source: CVE Program / CVE List V5
Vulnerability Description
Docker Model Runner (DMR) is software used to manage, run, and deploy AI models using Docker. Versions prior to 1.0.16 expose a POST `/engines/_configure` endpoint that accepts arbitrary runtime flags without authentication. These flags are passed directly to the underlying inference server (llama.cpp). By injecting the --log-file flag, an attacker with network access to the Model Runner API can write or overwrite arbitrary files accessible to the Model Runner process. When bundled with Docker Desktop (where Model Runner is enabled by default since version 4.46.0), it is reachable from any default container at model-runner.docker.internal without authentication. In this context, the file overwrite can target the Docker Desktop VM disk (`Docker.raw` ), resulting in the destruction of all containers, images, volumes, and build history. However, in specific configurations and with user interaction, it is possible to convert this vulnerability in a container escape. The issue is fixed in Docker Model Runner 1.0.16. Docker Desktop users should update to 4.61.0 or later, which includes the fixed Model Runner. A workaround is available. For Docker Desktop users, enabling Enhanced Container Isolation (ECI) blocks container access to Model Runner, preventing exploitation. However, if the Docker Model Runner is exposed to localhost over TCP in specific configurations, the vulnerability is still exploitable.
