CVE-2026-15974Public exploitNetwork attack vectorHinoki check available

Internal service and file access via unsanitized URLs

Published Jul 30, 2026 · Updated Jul 30, 2026

SSRF and local file access in SGLang 0 through 0.5.15 allow remote attackers to reach internal services and probe local files. The multimodal chat-completions media helpers pass unvalidated image, audio, and video URLs to HTTP fetching or local-path reads without private-address filtering or a destination allowlist. Reachability requires a multimodal inference route; valid media can be disclosed through model output, while other files expose an existence oracle.
