CVE-2025-6083Network attack vector

Cross-owner data disclosure via search filter bypass

Published Jun 13, 2025 · Updated Jun 17, 2025

Improper authorization in ExtremeCloud Universal ZTNA 25.2.0 allows remote authenticated users to search other owners' table data. A syntax error in the searchKeyword condition causes affected queries to omit the owner_id filter and scan the full table. Low-privileged access and active user interaction are required; the reported consequence is cross-owner data disclosure through search results.
