CVE-2022-21460Network attack vector

Authenticated database disclosure via undisclosed logging flaw

Published Apr 19, 2022 · Updated Sep 24, 2024

Information disclosure in Oracle MySQL Server 5.7.37 and earlier and 8.0.28 and earlier allows remote authenticated users to read database data. Oracle identifies Server: Logging as the affected component but has not published the flawed operation or the input that reaches it. Exploitation requires a highly privileged account, network access using MySQL Protocol, and high attack complexity; successful attacks expose critical data or all data accessible to the server.
