CVE-2026-82285

23th percentile - higher than 23% of all known CVEs

bisheng through 2.6.0-fix2 contains a server-side request forgery vulnerability in the POST /api/v1/workflow/report/callback endpoint that lacks authentication and applies no URL scheme restrictions or host filtering. Unauthenticated attackers can supply arbitrary URLs to enumerate internal network services and cloud metadata endpoints, then retrieve captured responses from object storage using caller-supplied object names.

The risk includes access to internal network resources and sensitive data such as cloud metadata, potentially leading to privilege escalation or information disclosure.

Update bisheng to a patched version and implement authentication and URL validation on the /callback endpoint. Also restrict access to this endpoint.
