CVE-2026-33990 Details
Description
Docker Model Runner (DMR) is software used to manage, run, and deploy AI models using Docker. Prior to version 1.1.25, 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. This issue has been patched in version 1.1.25. 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.
A server-side request forgery (SSRF) vulnerability has been identified in Docker Model Runner (DMR) versions prior to 1.1.25. This vulnerability arises in the OCI registry token exchange process, where Model Runner fails to properly validate the scheme, hostname, or IP range of the realm URL specified in the registry's WWW-Authenticate header. As a result, a malicious OCI registry could direct Model Runner to an internal URL, prompting it to make arbitrary GET requests to local services. The full response from these internal services would be reflected back to the caller. Furthermore, the token exchange mechanism could transmit data from these internal services back to the attacker-controlled registry via the Authorization: Bearer header.
Users should update Docker Model Runner to version 1.1.25 or later. For Docker Desktop users, version 4.67.0 or later includes the fixed Model Runner. Additionally, enabling Enhanced Container Isolation (ECI) can block container access to Model Runner, although this vulnerability may still be exploitable if Docker Model Runner is exposed to localhost over TCP in certain configurations.
