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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 25 Nov 2025
Detectable: no evidence on record.
No public nuclei template indexed

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

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 2026-10-26.

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

To mitigate CVE-2025-13643, European organizations should prioritize upgrading MongoDB Server to versions 7.0.26 or later and 8.0.14 or later once patches are available. In the interim, organizations should audit and minimize user privileges, ensuring that only trusted users have the ability to terminate queries. Implement role-based access control (RBAC) policies that restrict query termination capabilities to administrative roles. Monitor database logs for unusual query termination activities that could indicate exploitation attempts. Employ network segmentation and firewall rules to limit access to MongoDB instances to authorized personnel and systems only. Consider implementing query timeout and retry mechanisms in application logic to reduce the impact of unexpected query terminations. Regularly review MongoDB security advisories and apply security updates promptly. Additionally, conduct penetration testing and vulnerability assessments focused on authorization controls within MongoDB deployments to detect similar weaknesses.

Description

A user with access to the cluster with a limited set of privilege actions may be able to terminate queries that are being executed by other users. This may cause a denial of service by preventing a fraction of queries from successfully completing. This issue affects MongoDB Server v7.0 versions prior to 7.0.26 and MongoDB Server v8.0 versions prior to 8.0.14

Impact

For European organizations, the primary impact of CVE-2025-13643 is potential denial of service caused by unauthorized termination of database queries. This can disrupt business operations that depend on continuous and reliable database access, such as financial services, e-commerce platforms, healthcare systems, and public sector applications. Although the vulnerability does not expose sensitive data or allow data modification, the interruption of query execution can degrade service quality, cause transaction failures, and impact user experience. Organizations with multi-tenant MongoDB deployments or shared clusters are at higher risk, as malicious or compromised users with limited privileges could disrupt other users’ queries. The impact is more pronounced in environments with high query volumes or real-time data processing requirements. Given the low CVSS score and absence of known exploits, the immediate risk is moderate; however, unpatched systems could become targets for opportunistic attackers aiming to cause disruption. The vulnerability also highlights the importance of strict privilege management and monitoring in database environments.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
