CVE-2026-85976Network attack vectorHinoki check available

Response splitting via unsanitized file-exploration input

Published Oct 12, 2026 · Updated Oct 12, 2026

Response splitting in Progress MarkLogic Server Query Console allows attackers to alter client-side response handling via crafted input. The file-exploration endpoint insufficiently sanitizes supplied input; the specific parameter and sanitization failure are not detailed in the retrieved vendor material. Normal Query Console access requires the qconsole-user role, but exact exploit privileges and additional client-interaction requirements remain undocumented.
