Authenticated information disclosure via external XML entities
Published Mar 3, 2026 · Updated Mar 3, 2026
XXE in IBM InfoSphere Information Server 11.7.0.0 through 11.7.1.6 allows remote authenticated users to retrieve server data. IBM identifies external entity processing as the flaw but does not disclose the affected XML parser, input path, or operation that resolves attacker-controlled entities. Network access and a low-privileged account are required; exploitation exposes sensitive server information without user interaction.

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.
