Privileged data reads and modifications
Published Jan 21, 2025 · Updated Nov 3, 2025
Privilege flaw in MySQL Server allows remote authenticated users to read and modify data over the network in affected 8.x and 9.x releases. Oracle identifies Server: Security: Privileges as the affected component but has not published the faulty privilege-checking operation or code locus. Exploitation requires high MySQL privileges; the bounded impact is unauthorized reads, updates, inserts, or deletions of some server-accessible data.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=* <=8.0.40
- Affected versionversion=* <=8.4.3
- Affected versionversion=* <=9.1.0
