This metric measures the impact to the availability of the impacted component resulting from a successfully exploited vulnerability. It refers to the loss of availability of the impacted component itself, such as a networked service (e.g., web, database, email). Since availability refers to the accessibility of information resources, attacks that consume network bandwidth, processor cycles, or disk space all impact the availability of an impacted component.

Availability

There is no impact to availability within the impacted component.

None

This metric describes the conditions beyond the attacker’s control that must exist in order to exploit the vulnerability. Such conditions may require the collection of more information about the target or computational exceptions. The assessment of this metric excludes any requirements for user interaction in order to exploit the vulnerability. If a specific configuration is required for an attack to succeed, the Base metrics should be scored assuming the vulnerable component is in that configuration.

Attack Complexity

Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.

This metric reflects the context by which vulnerability exploitation is possible. The Base Score increases the more remote (logically, and physically) an attacker can be in order to exploit the vulnerable component.

Attack Vector

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).

Network

This metric measures the impact to the confidentiality of the information resources managed by a software component due to a successfully exploited vulnerability. Confidentiality refers to limiting information access and disclosure to only authorized users, as well as preventing access by, or disclosure to, unauthorized ones.

Confidentiality

There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.

This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information.

Integrity

Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.

This metric describes the level of privileges an attacker must possess before successfully exploiting the vulnerability.

Privileges Required

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.

Does a successful attack impact a component other than the vulnerable component? If so, the Base Score increases and the Confidentiality, Integrity and Authentication metrics should be scored relative to the impacted component.

Scope

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.

Unchanged

This metric captures the requirement for a user, other than the attacker, to participate in the successful compromise the vulnerable component. This metric determines whether the vulnerability can be exploited solely at the will of the attacker, or whether a separate user (or user-initiated process) must participate in some manner.

User Interaction

The vulnerable system can be exploited without any interaction from any user.

FIRST CVSS v3.1

FIRST CVSS v4.0

CVE-2025-64687 is a vulnerability identified in JetBrains YouTrack, a widely used issue tracking and project management software. The vulnerability is characterized by a CVSS 3.1 vector of AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N, indicating that it can be exploited remotely over the network with low attack complexity and requires low privileges but no user interaction. The scope remains unchanged, and the impact affects confidentiality and integrity to a limited extent, with no impact on availability. Although the specific affected versions and technical details are not disclosed, the vulnerability likely allows an attacker with some level of access to extract sensitive information or alter data within the YouTrack environment. No known exploits have been reported in the wild, and no patches have been published yet. The vulnerability was reserved and published in November 2025, suggesting it is a recent discovery. Given YouTrack's role in managing project workflows and potentially sensitive project data, exploitation could lead to unauthorized data exposure or manipulation, impacting organizational operations and trust. The lack of user interaction requirement and network accessibility increases the risk profile, especially in environments where privilege separation is weak or where YouTrack is exposed to untrusted networks.
