Scope: Changed
Confidentiality: High
Integrity: High
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: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
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: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 10 Nov 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

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 2026-10-26.

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.

What to do

AI-suggested

1. Monitor JetBrains official channels for patches or updates addressing CVE-2025-64689 and apply them immediately upon release. 2. Restrict network access to YouTrack instances using firewalls and VPNs to limit exposure to trusted users and IP ranges. 3. Enforce the principle of least privilege by auditing and minimizing user permissions within YouTrack, ensuring no unnecessary elevated privileges are granted. 4. Implement robust authentication mechanisms, such as multi-factor authentication (MFA), to reduce the risk of credential compromise. 5. Continuously monitor logs and user activities for unusual behavior indicative of exploitation attempts or privilege escalation. 6. Conduct regular security assessments and penetration testing focused on YouTrack deployments to identify potential weaknesses. 7. Educate administrators and users about the risks and signs of exploitation related to this vulnerability. 8. Consider network segmentation to isolate YouTrack servers from critical infrastructure to limit lateral movement in case of compromise.

Impact

For European organizations, the impact of CVE-2025-64689 could be substantial, especially for those relying on YouTrack for managing software development, bug tracking, and project workflows. Confidentiality breaches could expose sensitive project data, intellectual property, or customer information, leading to reputational damage and regulatory penalties under GDPR. Integrity compromise could result in unauthorized changes to issue statuses, project timelines, or audit trails, disrupting operational processes and decision-making. Since availability is not impacted, denial-of-service is unlikely, but the stealthy nature of confidentiality and integrity breaches may delay detection. Organizations in sectors such as finance, technology, and government, which often use JetBrains products, may face increased risk. The vulnerability's remote exploitability and low complexity make it attractive for attackers seeking to gain footholds or escalate privileges within corporate networks.

Summary

CVE-2025-64689 is a vulnerability identified in JetBrains YouTrack, a widely used issue tracking and project management software. The vulnerability has a CVSS 3.1 vector of AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N, indicating that it is remotely exploitable over the network with low attack complexity and requires low privileges but no user interaction. The scope is changed, meaning the vulnerability affects resources beyond the initially vulnerable component. The impact on confidentiality and integrity is high, while availability is not affected. This suggests that an attacker with low-level access could escalate privileges or manipulate data, potentially gaining unauthorized access to sensitive project information or altering issue tracking data. No affected versions or patches have been specified yet, and no known exploits are reported in the wild. The vulnerability was reserved and published in November 2025 by JetBrains, indicating recent discovery. The lack of detailed technical information limits precise exploitation methods, but the CVSS vector implies a critical security flaw that could be leveraged in targeted attacks or insider threat scenarios.
