Authenticated service hang or crash via JSON Duality
Published Jul 21, 2026 · Updated Jul 21, 2026
Denial of service in Oracle MySQL Server and MySQL Cluster 9.7.0 through 9.7.1 allows remote authenticated users to hang or crash servers. Oracle identifies the Server: JSON Duality component but has not published the malformed operation or input that triggers the failure. High-privilege database access over a supported network protocol is required, and exploitation causes a hang or repeatable crash without reported data disclosure or modification.
