Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Information Schema). Supported versions that are affected are 8.0.0-8.0.45, 8.4.0-8.4.8 and 9.0.0-9.6.0. Easily exploitable vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized read access to a subset of MySQL Server accessible data. CVSS 3.1 Base Score 4.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N).
AnalysisAI
Information disclosure in Oracle MySQL Server's Information Schema component exposes a subset of server data to authenticated low-privileged network attackers across three major release branches (8.0.0-8.0.45, 8.4.0-8.4.8, and 9.0.0-9.6.0). The flaw is exploitable via multiple protocols with low attack complexity but requires a valid database account, limiting opportunistic mass exploitation. No public exploit exists and this vulnerability is absent from the CISA KEV catalog; an EPSS score of 0.03% at the 8th percentile reflects negligible observed exploitation pressure.
Technical ContextAI
MySQL Server's Information Schema is a read-only set of virtual tables providing metadata about databases, tables, columns, privileges, and server internals. CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) indicates insufficient access enforcement on Information Schema views or underlying system catalog queries, allowing a low-privileged user to retrieve data beyond their intended authorization scope. This class of flaw typically arises when privilege checks are applied inconsistently across metadata access paths - for example, when a user can query INFORMATION_SCHEMA.COLUMNS or similar views to enumerate objects they cannot otherwise access. The CPE string cpe:2.3:a:oracle_corporation:mysql_server identifies all affected Oracle MySQL Server builds across the 8.0, 8.4, and 9.x release branches. Tags referencing Red Hat and SUSE indicate the vulnerability is present in downstream distribution packages for those platforms.
RemediationAI
Apply the Oracle Critical Patch Update released in April 2026, detailed at https://www.oracle.com/security-alerts/cpuapr2026.html. Exact fixed release versions are not independently confirmed from the available intelligence - the Oracle advisory should be consulted for precise upgrade targets beyond 8.0.45, 8.4.8, and 9.6.0 respectively. Red Hat and SUSE customers should additionally monitor their vendor errata channels for updated MySQL packages. As a compensating control where patching cannot be applied immediately, restrict MySQL network access to known trusted application and administrative hosts using firewall rules or MySQL's own bind-address and host-based account restrictions, reducing the network attack surface. Auditing and minimizing low-privileged account grants - particularly for accounts with no business need to query Information Schema - further limits exposure. Neither workaround eliminates the underlying flaw and patching remains the authoritative fix.
