CVE-2026-60623 in MySQL Connectors
Summary
by MITRE • 07/22/2026
Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/J). Supported versions that are affected are 9.7.0-9.7.1. Difficult to exploit vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Connectors. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all MySQL Connectors accessible data as well as unauthorized access to critical data or complete access to all MySQL Connectors accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Connectors. CVSS 3.1 Base Score 7.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L).

Analysis
by VulDB Data Team • 07/22/2026
This vulnerability exists within Oracle MySQL Connectors, specifically in the Connector/J component affecting versions 9.7.0 through 9.7.1. The flaw represents a significant security weakness that can be exploited by adversaries with minimal privileges and network access through multiple protocols. The vulnerability's classification as difficult to exploit indicates that while the attack vector requires some technical knowledge or preparation, it remains a genuine threat to MySQL deployments using these affected versions.
The technical nature of this vulnerability stems from insufficient access controls within the Connector/J component, allowing low privilege attackers to gain unauthorized access to critical database resources. This flaw manifests through multiple network protocols, expanding the potential attack surface and making detection more challenging for security monitoring systems. The vulnerability's impact spans all three core principles of information security: confidentiality, integrity, and availability, as demonstrated by the CVSS 3.1 score of 7.1 which reflects high severity across these domains.
From an operational perspective, successful exploitation can result in substantial data compromise including unauthorized creation, deletion, or modification of critical database content. Attackers can potentially access all data accessible through the affected MySQL Connectors, making this vulnerability particularly dangerous for applications that rely on proper data integrity and confidentiality controls. Additionally, the vulnerability enables partial denial of service conditions that can disrupt database operations and impact business continuity, with attackers capable of causing system unavailability affecting database connectivity and application functionality.
The security implications extend beyond immediate data compromise to include potential long-term operational damage through unauthorized system access and data manipulation. Organizations using affected MySQL Connectors versions face elevated risk of data breaches, regulatory compliance violations, and operational disruption that could impact customer trust and business operations. The CVSS vector analysis indicates network accessibility with high attack complexity and low privilege requirements, suggesting that this vulnerability may be exploited by both external attackers and insider threats with appropriate network access.
Mitigation strategies should prioritize immediate patching of affected systems to version 9.7.2 or later, which addresses the identified access control weaknesses. Organizations should implement network segmentation and access controls to limit exposure of MySQL Connectors to unauthorized network traffic, following principle of least privilege configurations for database connections. Security monitoring should be enhanced to detect unusual connection patterns or unauthorized data access attempts, with regular vulnerability scanning to identify any remaining unpatched systems within the environment. The vulnerability aligns with CWE-284 (Improper Access Control) and may map to ATT&CK techniques involving privilege escalation and credential access, requiring comprehensive security posture assessment and remediation across all affected database components.
This vulnerability highlights the critical importance of maintaining up-to-date database connector software and implementing robust network security controls. Organizations should conduct thorough risk assessments for all systems utilizing affected MySQL Connectors versions, review existing access control configurations, and establish monitoring procedures to detect potential exploitation attempts. The combination of high confidentiality and integrity impacts with partial availability concerns makes this vulnerability particularly significant for organizations handling sensitive data through MySQL database connections, requiring immediate attention through coordinated patch management and security configuration reviews.
