Sensitive-data disclosure through HTTP response reflection
Published Aug 21, 2026 · Updated Aug 21, 2026
Information disclosure in Esri Portal for ArcGIS 11.1 through 12.0 allows remote attackers to expose sensitive data in HTTP responses. Esri states that sensitive information is reflected in a response body but has not disclosed the affected endpoint or the operation that selects the data. Authentication is not required, although high-complexity, difficult-to-reproduce conditions limit reachability; the reported consequence is disclosure only.

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.
