How to Fix CVE-2026-33990

To remediate this vulnerability, upgrade all affected Github.com/docker/model runner dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/docker/model-runner fixed: 1.1.25 
Upgrade github.com/docker/model-runner to 1.1.25
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/docker/model-runner

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-33990, inspect your project dependencies for Github.com/docker/model runner:

inspect dependencies for github.com/docker/model-runner

Analyze the terminal output to locate any version of Github.com/docker/model runner in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.25), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Github.com/docker/model runner, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Summary Docker Model Runner contains an SSRF vulnerability in its OCI registry token exchange flow. When pulling a model, Model Runner follows the realm URL from the registry's `WWW-Authenticate` header without validating the scheme, hostname, or IP range. A malicious OCI registry can set the realm to an internal URL (e.g., `http://127.0.0.1:3000/`), causing Model Runner running on the host to make arbitrary GET requests to internal services and reflect the full response body back to the caller. Additionally, the token exchange mechanism can relay data from internal services back to the attacker-controlled registry via the `Authorization: Bearer` header. ## Patches Fixed in Docker Model Runner v1.1.25 Docker Desktop users should update to 4.67.0 or later, which includes the fixed Model Runner. ## Workarounds 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. ## Impact An unprivileged container or a malicious OCI registry that the user performed a pull from might issue GET requests to host-local services (localhost, internal network)
