Exploitation Conditions

Exploitation requires network access to a target running MySQL Connector/J versions 9.7.0 or 9.7.1 specifically (the 9.7.x line), and the attacker must already hold low privileges (CVSS PR:L) - so it is not fully unauthenticated despite the 'Authentication Bypass' tag, which appears to describe the flaw's effect rather than removing the PR:L prerequisite. The vendor notes exploitation is possible 'via multiple protocols,' broadening the reachable attack surface. Limiting factors: only the 9.7.0-9.7.1 releases are affected (earlier or later fixed builds are not), impact is confined to confidentiality (no data modification or denial of service), and the attacker needs an existing low-privilege position plus network reachability to the vulnerable component. The exact protocol conditions are not detailed in the Oracle CPU summary and should be confirmed against the advisory.

Impact

The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N, score 7.7) indicates a network-reachable, low-complexity attack requiring only low privileges and no user interaction, with a scope change amplifying impact to other products - a genuinely serious profile for a data-confidentiality flaw. However, no EPSS score, KEV status, POC, or SSVC decision data was supplied, so real-world exploitation likelihood cannot be quantified from the input; the absence of these signals is a data gap, not evidence of low risk. A notable tension exists between the 'Authentication Bypass' tag (which colloquially implies no auth) and the CVSS PR:L metric (which requires the attacker to already hold low privileges) - this should be verified against Oracle's advisory, as it materially changes who can exploit the issue. Oracle CPU disclosures are historically terse and rarely accompanied by technical detail, so treat the exact mechanism as unconfirmed. Overall this warrants prioritized patching given the driver's broad deployment and network attack vector, but the missing exploitability telemetry means it is not confirmed to be under active attack.

Exploit ScenarioDerived

An attacker with a foothold as a low-privileged user on the network path to an application that uses Connector/J 9.7.0/9.7.1 abuses the driver's connection/authentication handling to read data it should not be able to access, and - thanks to the scope change - reaches sensitive data belonging to the connected application or other products. Because attack complexity is low and no user interaction is required, exploitation can be scripted once the technique is known. No public exploit code has been identified at time of analysis.

AnalysisAIv1 – Jul 22, 2026

Unauthorized data disclosure in Oracle MySQL Connector/J (the official MySQL JDBC driver) versions 9.7.0 through 9.7.1 allows a low-privileged attacker with network access to compromise confidentiality, with a scope change that lets the attack significantly impact additional products beyond the connector itself. Fixed in the Oracle Critical Patch Update of July 2026 and tagged as an authentication bypass, the flaw carries a CVSS 3.1 score of 7.7 with high confidentiality impact and no integrity or availability effect. No public exploit identified at time of analysis, and there is no CISA KEV or EPSS signal in the provided data.

RemediationAI

Upgrade MySQL Connector/J to the fixed release delivered in the Oracle Critical Patch Update of July 2026 (https://www.oracle.com/security-alerts/cpujul2026.html); the input does not name an exact fixed version number, so consult that advisory for the precise patched build rather than relying on an assumed version. In Java projects this means bumping the mysql-connector-j dependency in Maven/Gradle and redeploying affected applications. Until patched, reduce exposure by restricting which hosts can reach MySQL endpoints the vulnerable driver connects to, enforcing TLS and strict server-certificate/host verification on JDBC connections, and limiting the privileges of the database accounts the connector uses so a confidentiality breach yields less data - noting the trade-off that tightening host verification can break connections to servers with mismatched or self-signed certificates and must be tested before rollout. Because the flaw is tagged as an authentication bypass, also review connection-string trust settings against Oracle's guidance.

Technical ContextAI · show details

MySQL Connector/J is Oracle's official Type 4 JDBC driver used by Java applications to connect to MySQL databases over the wire protocol (and, per the advisory, 'multiple protocols'). Because the driver sits between an application and its database, a defect in how it handles connections, authentication, or protocol data can expose data belonging to the calling application rather than just the driver - which is reflected in the CVSS scope change (S:C). No CWE was assigned in the source data, but the vendor 'Authentication Bypass' tag together with a confidentiality-only impact (C:H, I:N, A:N) points to a root cause in connection authentication or trust handling that permits reading data the attacker should not reach. Exact affected components are the 9.7.x release line (9.7.0 and 9.7.1) per Oracle's July 2026 Critical Patch Update.

DescriptionCVE.org

Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/J). Supported versions that are affected are 9.7.0-9.7.1. Easily exploitable vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Connectors. While the vulnerability is in MySQL Connectors, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all MySQL Connectors accessible data. CVSS 3.1 Base Score 7.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N).

Executive ViewAI

Why It Matters

Oracle MySQL Connector/J versions 9.7.0-9.7.1 contain an authentication bypass vulnerability enabling unauthorized database data disclosure via network access. Organizations operating Java applications with these connector versions risk confidential database information exposure and potential lateral movement through connected systems. This impacts any enterprise with production MySQL database connectivity using the official JDBC driver in affected versions.

Business Impact: High
Compensating Controls

Apply vendor patch: Oracle Critical Patch Update of July 2026. If patch deployment is delayed, implement network segmentation, enhanced database connection logging, credential rotation to enforce least-privilege database accounts, and consider downgrading to Connector/J 9.6.x pending patch availability.
