CVE-2026-9372Public exploitNetwork attack vector

Unauthenticated internal service access via unchecked baseURL

Published May 24, 2026 · Updated May 24, 2026

SSRF in ItzCrazyKns Vane 1.12.0 through 1.12.1 allows remote attackers to read internal service data via the Model Provider API. The unauthenticated POST /api/providers route accepts an arbitrary baseURL, then provider code fetches a derived model-list path without blocking loopback, private, or link-local targets. A network-reachable instance is the only gate; responses expose expected JSON data or parser-error fragments and support internal service probing.
