CVE-2025-50100Network attack vector

High-privilege partial service interruption

Published Jul 15, 2025 · Updated Jul 17, 2025

Resource consumption in Oracle MySQL Server affected releases allows remote authenticated users to partially interrupt the database service. Oracle identifies the locus as Server: Thread Pooling but has not disclosed the operation that mishandles attacker-controlled activity. Exploitation requires high database privileges, network access via a supported protocol, and high attack complexity; affected versions are 8.0.0 through 8.0.42, 8.4.0 through 8.4.5, and 9.0.0 through 9.3.0.
