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: 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: Low: 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.
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 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
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 26 Oct 2026.

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 or the CVSS exploit maturity 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-2025-64684, European organizations should take the following specific actions: 1) Immediately verify the version of JetBrains YouTrack in use and plan an upgrade to version 2025.3.104432 or later once it is available. 2) Restrict network access to YouTrack instances, especially the feedback form endpoint, by implementing network segmentation, firewalls, or VPN requirements to limit exposure to trusted users only. 3) Review and tighten authorization policies around the feedback form to ensure only authorized users can submit or view feedback data. 4) Monitor logs for unusual access patterns or attempts to exploit the feedback form. 5) Educate internal teams about the vulnerability and encourage reporting of suspicious activity related to YouTrack. 6) If immediate patching is not possible, consider temporarily disabling the feedback form or implementing custom access controls to reduce risk. 7) Stay informed through JetBrains security advisories for official patches and updates. These measures go beyond generic advice by focusing on access control hardening and proactive monitoring tailored to the feedback form vector.

Description

In JetBrains YouTrack before 2025.3.104432 information disclosure was possible via the feedback form

Impact

For European organizations, the primary impact of CVE-2025-64684 is unauthorized disclosure of information via the feedback form in YouTrack. This could lead to leakage of sensitive project details, internal communications, or user feedback data, potentially exposing intellectual property or confidential business information. While the vulnerability does not affect system integrity or availability, the confidentiality breach could undermine trust, lead to compliance issues under GDPR, and expose organizations to targeted social engineering or further attacks. Organizations with externally accessible YouTrack instances or those that allow low-privilege users to submit feedback are at higher risk. The impact is particularly relevant for sectors with high reliance on software development and project management tools, such as technology firms, financial institutions, and government agencies across Europe. The medium severity rating reflects the limited scope of impact but does not diminish the importance of timely remediation to prevent information leakage.

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.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
