vulnerability.

  - 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. (CVE-2026-33990)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
