CVE-2026-12798Public exploitNetwork attack vector

Authenticated internal resource access via unvalidated spec URL

Published Jun 21, 2026 · Updated Jun 21, 2026

SSRF in LiteLLM 1.82.0 through 1.82.2 allows remote authenticated users to access internal services via a crafted OpenAPI spec URL. The load_openapi_spec_async function passes the request-supplied spec_path directly to an HTTP client's GET method without destination validation. A valid API key and the default-enabled MCP REST API are required; returned responses expose internal content and distinguish reachable ports.
