Authenticated data disclosure via out-of-bounds read
Published Oct 17, 2023 · Updated Jun 12, 2025
Out-of-bounds read in MySQL Server 8.0.33 and earlier allows remote authenticated users to read a subset of server-accessible data. The Server: Security: Encryption component reads beyond a buffer boundary, but Oracle has not identified the affected routine or attacker-controlled input. Exploitation requires a high-privilege account with network access over the MySQL Protocol and affects confidentiality only.
