Confidentiality: None
Integrity: Low
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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: Low: 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.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 11 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

Monitor JetBrains communications closely for the official patch release addressing CVE-2025-64773 and apply updates promptly to affected YouTrack instances.
Until patched, enforce strict access controls limiting high-privilege accounts to trusted personnel only, reducing the risk of exploitation.
Implement multi-factor authentication (MFA) for all privileged users to mitigate risks from compromised credentials.
Regularly audit helpdesk agent role assignments and logs to detect anomalies or unauthorized increases in agent counts.
Consider deploying rate limiting or concurrency controls at the network or application layer to reduce the likelihood of race condition exploitation.
Educate administrators and helpdesk managers about the vulnerability and encourage vigilance for suspicious activity.
If feasible, isolate YouTrack instances handling sensitive data within secure network segments to limit exposure.
Review and tighten internal policies governing agent role provisioning and approval workflows to add additional oversight.

Description

In JetBrains YouTrack before 2025.3.104432 a race condition allowed bypass of helpdesk Agent limit

Impact

For European organizations, the primary impact of CVE-2025-64773 lies in the potential unauthorized escalation of helpdesk agent roles within JetBrains YouTrack. This could lead to operational risks such as unauthorized ticket handling, policy circumvention, or insider threat exploitation. Although confidentiality and availability are not directly affected, integrity concerns arise from the ability to bypass agent limits, potentially undermining role-based access controls and audit processes. Organizations with strict compliance requirements or sensitive customer support data may face increased risk of internal misuse or regulatory scrutiny if agent roles are improperly assigned. The requirement for high privileges and authenticated access reduces the likelihood of external attackers exploiting this vulnerability, but insider threats or compromised privileged accounts remain a concern. Given YouTrack's role in managing issue tracking and customer support workflows, any disruption or unauthorized access could impact service quality and organizational reputation. European entities should consider this vulnerability in their risk assessments, especially those with large helpdesk teams or complex role management policies.

CWE-362Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') (opens in a new tab)
Class weaknessLikelihood of exploit: MediumOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
Architecture and Design
In languages that support it, use synchronization primitives. Only wrap these around critical code to minimize the impact on performance.
Architecture and Design
Use thread-safe capabilities such as the data access abstraction in Spring.
Architecture and Design
Minimize the usage of shared resources in order to remove as much complexity as possible from the control flow and to reduce the likelihood of unexpected conditions occurring.
