Attack Vector: Network
Attack Complexity: High
Privileges Required: Low
User Interaction: None
Scope: Unchanged
Confidentiality: High
Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 15 Apr 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Apply official patches or updates from Oracle as soon as they become available for the affected MySQL Cluster versions. 2. Restrict network access to MySQL Cluster clients by implementing strict firewall rules and network segmentation to limit exposure to trusted hosts and networks only. 3. Use encrypted connections (e.g., TLS) for MySQL Cluster communications to reduce the risk of interception or man-in-the-middle attacks. 4. Monitor database logs and network traffic for unusual access patterns or unauthorized data modification attempts, employing anomaly detection tools where possible. 5. Implement least privilege principles for database users and service accounts interacting with MySQL Cluster to minimize potential damage from compromised clients. 6. Regularly audit MySQL Cluster configurations and client deployments to ensure they do not expose unnecessary network services or protocols. 7. Educate database administrators and security teams about this vulnerability and encourage proactive incident response planning. 8. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts targeting MySQL Cluster protocols.

Description

Vulnerability in the MySQL Client product of Oracle MySQL (component: Client: mysqldump). Supported versions that are affected are 8.0.0-8.0.41, 8.4.0-8.4.4 and 9.0.0-9.2.0. Difficult to exploit vulnerability allows low privileged attacker with network access via multiple protocols to compromise MySQL Client. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all MySQL Client accessible data as well as unauthorized update, insert or delete access to some of MySQL Client accessible data. CVSS 3.1 Base Score 5.9 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:N).

Impact

For European organizations, this vulnerability poses a risk of unauthorized data disclosure and unauthorized data modification within MySQL Cluster environments. Organizations that rely on MySQL Cluster for critical applications, including financial services, healthcare, telecommunications, and government infrastructure, may face confidentiality breaches exposing sensitive personal or corporate data. Integrity impacts could lead to data corruption or manipulation, potentially disrupting business operations or causing compliance violations under regulations such as GDPR. Although exploitation is difficult, the broad network access vector and lack of required user interaction increase the attack surface, especially in complex networked environments. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits over time. The impact is heightened in sectors where MySQL Cluster is used for high-availability and distributed database solutions, common in large enterprises and service providers across Europe.
