CVE-2020-2694Network attack vector

Authenticated data disclosure through undisclosed Information Schema flaw

Published Jan 15, 2020 · Updated Sep 30, 2024

Information disclosure in Oracle MySQL Server 8.0.18 and earlier allows remote authenticated users to read a subset of accessible data. The flaw resides in Server: Information Schema, but Oracle has not published the faulty operation or crafted input that triggers disclosure. Exploitation requires a low-privileged account, network access over a supported protocol, and high-complexity conditions; integrity and availability are unaffected.
