CVE-2026-82285Public exploitNetwork attack vector

Unauthenticated internal response disclosure via callback fetch

Published Aug 28, 2026 · Updated Aug 28, 2026

Server-side request forgery in DataElem BISHENG 2.6.0-fix2 and earlier allows remote attackers to read internal service responses. The unauthenticated POST /api/v1/workflow/report/callback handler passes a caller-supplied URL to Requests().get without scheme or host validation, then writes the response body to MinIO under a caller-derived object name. Network access to the API is sufficient to probe internal services or cloud metadata endpoints and recover stored response content.
