Unauthenticated blind SSRF via unvalidated delegation URI
Published May 5, 2026 · Updated May 5, 2026
Blind SSRF in Eclipse BaSyx Java Server SDK before 2.0.0-milestone-10 allows remote attackers to send arbitrary HTTP POST requests. HTTPOperationDelegation takes the invocationDelegation qualifier value as a URI and passes it directly to a bare Spring WebClient without host or address validation. Unauthenticated access to the BaSyx HTTP APIs is sufficient to reach loopback, private-network, or cloud metadata endpoints, although responses are not returned directly.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
