CVE-2026-69228Network attack vector

Unauthenticated access to a protected resource

Published Aug 21, 2026 · Updated Aug 21, 2026

Missing authentication in Esri Portal for ArcGIS 11.1 through 12.0 allows remote attackers to read a protected non-user resource. Request processing permits access without authentication, but Esri has not disclosed the resource, endpoint, handler, or omitted enforcement operation. No account or user interaction is required; reported impact is limited to reading that resource, with no user-content, integrity, or availability impact.
