CVE-2024-21243Network attack vector

High-privilege disclosure of server-accessible data

Published Oct 15, 2024 · Updated Nov 3, 2025

Information disclosure in Oracle MySQL Server 8.4.2 and earlier and 9.0.1 and earlier allows remote authenticated users to read server data. Oracle identifies Server: Telemetry as the affected component but has not disclosed the specific locus or operation that mishandles data. Exploitation requires high privileges and high attack complexity, and disclosure is limited to a subset of data accessible to the server.
