CVE-2025-50081 is a vulnerability identified in the MySQL Client component (specifically mysqldump) of Oracle's MySQL Cluster product, affecting versions 7.6.0, 8.0.0 through 8.0.42, 8.4.0 through 8.4.5, and 9.0.0 through 9.3.0. The vulnerability allows a high-privileged attacker with network access via multiple protocols to compromise the MySQL Client. Exploitation is difficult and requires human interaction from a person other than the attacker, indicating a social engineering or indirect interaction vector. Successful exploitation can lead to unauthorized read access to a subset of MySQL Client accessible data and unauthorized update, insert, or delete operations on some of the data accessible through MySQL Client. The CVSS 3.1 base score is 3.1, reflecting low severity, with impacts limited to confidentiality and integrity but no availability impact. The attack vector is network-based (AV:N), with high attack complexity (AC:H), requiring high privileges (PR:H) and user interaction (UI:R). The scope is unchanged (S:U), and the impacts on confidentiality and integrity are low (C:L, I:L), with no availability impact (A:N). The vulnerability is categorized under CWE-284, indicating an authorization bypass or insufficient access control issue. No known exploits are currently reported in the wild, and no patches are linked yet. The vulnerability affects the MySQL Client, which is commonly used for database management and backup operations, especially via mysqldump, which is often used for data export. The requirement for high privileges and user interaction limits the ease of exploitation but still poses a risk in environments where attackers have elevated access and can trick legitimate users into performing actions that enable the exploit.

For European organizations, the impact of CVE-2025-50081 is primarily on the confidentiality and integrity of data managed within MySQL Cluster environments. Unauthorized read access could expose sensitive business or customer data, while unauthorized modifications could lead to data corruption, loss of data integrity, or unauthorized changes in critical datasets. Given that MySQL Cluster is often used in high-availability and distributed database scenarios, any unauthorized data manipulation could disrupt business processes or lead to compliance violations under regulations such as GDPR. However, the requirement for high privileges and user interaction reduces the likelihood of widespread exploitation. Organizations with complex database environments and multiple users with elevated privileges are at higher risk, especially if social engineering tactics are successful. The absence of availability impact means service disruption is unlikely, but data integrity and confidentiality breaches could still have significant reputational and regulatory consequences.

European organizations should implement the following specific mitigations: 1) Restrict high-privilege access to MySQL Client environments strictly on a need-to-know basis and enforce the principle of least privilege to minimize the number of users who could exploit this vulnerability. 2) Educate and train users with elevated privileges on social engineering risks and the importance of cautious interaction with network requests or prompts that could trigger the vulnerability. 3) Monitor and audit MySQL Client usage, especially mysqldump operations, to detect unusual or unauthorized data access or modification attempts. 4) Implement network segmentation and firewall rules to limit network access to MySQL Clients only from trusted and authenticated sources, reducing the attack surface. 5) Stay updated with Oracle's security advisories and apply patches or updates promptly once available, as no patch links are currently provided. 6) Employ multi-factor authentication (MFA) for administrative access to MySQL environments to add an additional layer of security against unauthorized access. 7) Use database activity monitoring tools to detect anomalous queries or data manipulation patterns that could indicate exploitation attempts.
